One-to-one tutors for the Foundation papers of OCR Gateway Physics A (J249) and Twenty First Century Physics B (J259)
Book a Free ConsultationLeading Tuition’s OCR GCSE Physics Foundation tier tutoring prepares students for the Foundation papers of Gateway Physics A (J249) and Twenty First Century Physics B (J259), which OCR’s specifications say assess grades 5 to 1. Each Foundation entry is made up of papers worth 90 marks, and every programme is built around the code the student’s school has entered.
OCR runs both Physics GCSEs side by side, and their Foundation papers are different. Check the code first; our overview of the OCR GCSE Physics specifications J249 and J259 covers both courses.
Our expert GCSE Physics tutors help students working at the Foundation tier of OCR Gateway Physics A (J249) and Twenty First Century Physics B (J259), building each programme around the paper code the school has entered and the equations on OCR’s own sheet.
OCR’s Physics equation sheets carry the key “HT = Higher Tier only”, which draws a clear line between the tiers. Each sheet is headed with its code and the component numbers 01/02/03/04. The J249 sheet is headed “J249 01/02/03/04” and the J259 sheet “J259 01/02/03/04”.
| Code | Sheet and series | Equations OCR prints with HT |
|---|---|---|
| J249 Gateway Physics A | Equation Sheet, J249 01/02/03/04, June 2026 | pressure due to a column of liquid = height of column × density of liquid × gravitational field strength (p = hρg); momentum = mass × velocity (p = mv); force on a conductor (F = BIl); the transformer ratio Vp/Vs = Np/Ns |
| J259 Twenty First Century Physics B | Equation Sheet, J259 01/02/03/04, June 2026 | force = magnetic flux density × current × length of conductor (F = BIl); the transformer ratio Vp/Vs = Np/Ns; momentum = mass × velocity (p = mv); change in momentum = resultant force × time for which it acts (Δp = Ft); pressure = density × gravitational field strength × depth (p = ρgh) |
On both sheets, wave speed (v = fλ), potential difference = current × resistance (V = IR), power = potential difference × current (P = VI), power = current2 × resistance (P = I2R) and energy transferred = power × time (E = Pt) are printed without the HT prefix. The J259 sheet prints VpIp = VsIs without an HT mark, directly before the HT-marked turns ratio, and the J249 sheet prints the same relationship under P8 Global challenges, also without HT. OCR’s June 2025 sheets for each code list the same equations as the sheets in the table; only the series date and print codes differ.
The specifications also split their equations. J249 lists some equations under “recall and apply” and others under “select and apply”, and J259 does the same in its parts (a) and (b). In J249 the “select and apply” list includes change in thermal energy = mass × specific heat capacity × change in temperature, and (final velocity)2 − (initial velocity)2 = 2 × acceleration × distance. In J259 part (b) includes (final speed)2 − (initial speed)2 = 2 × acceleration × distance and the change-of-state relationship, energy to cause a change of state = mass × specific latent heat.
The examiners’ reports show why this matters on the Foundation papers. In J249/01 the report says most candidates across the range could write down density = mass/volume from the equation sheet, and that the most common reason for a wrong answer was incorrect rearranging. In J259/01 it says candidates did well where they were given the equation or told to use the Equation Sheet.
What this changes in our programme. A Foundation session never spends time on the HT-marked equations. Instead the tutor drills the sequence the J249 report describes: write the equation from the sheet, substitute with units converted, then rearrange. Students practise rearranging a = b × c and a = b/c forms until it is automatic, because that is where the J249/01 marks went.
The J249 specification says: “Statements shown in bold type will only be tested in the Higher Tier papers. All other statements will be assessed in both Foundation and Higher Tier papers.” The table below reads that marking from the font data of the specification PDF, not from extracted text, so a statement appears as Higher-only only where its words are in bold type. Where Foundation covers part of a topic, the plain-type outcome sits in the middle column.
| Topic in J249 | Plain type (assessed on both tiers) | Bold type (Higher Tier papers only) |
|---|---|---|
| P2.1 Motion | P2.1e: relate changes and differences in motion to distance-time and velocity-time graphs; interpret lines and slopes | P2.1f: interpret enclosed area in velocity-time graphs |
| P2.2 Newton’s laws | P2.2d: apply Newton’s first law; P2.2i: apply Newton’s second law in calculations relating forces, masses and accelerations | P2.2e: vector diagrams to illustrate resolution of forces, with scale drawings limited to parallel and perpendicular vectors; P2.2f to P2.2h: forces on an isolated object or system, free body diagrams, terminal velocity; P2.2j: inertial mass; P2.2k: momentum and collisions; P2.2q: circular motion at constant speed; and the momentum equation PM2.2ii |
| P1.3 Pressure | P1.3e: how doing work on a gas can increase its temperature (a bicycle pump); P1.3h: factors influencing floating and sinking; P1.3i: pressure in a liquid and the upwards force on a partially submerged object; P1.3j: pressure differences at different depths, with g = 10 N/kg; and the liquid-pressure equation PM1.3ii | |
| P4.2 Uses of magnetism | Every outcome from P4.2a (the force between a magnet and a current-carrying conductor) to P4.2j (microphones, loudspeakers and headphones): Fleming’s left-hand rule, the force equation, electric motors, induction, alternators and dynamos, transformers | |
| P5 Waves in matter | P5.1h and P5.1i: sound and vibrations in solids, and the limited frequency range of hearing; P5.2i: wave detection of structures hidden in our bodies; P5.2j: radio waves and oscillations in electrical circuits; P5.3a and P5.3b: absorption, transmission, refraction and reflection of electromagnetic waves by different substances | |
| P6.1 Radioactive emissions | P6.1j: explain the concept of half-life and its link to the random nature of decay | P6.1k: calculate the net decline, expressed as a ratio, after a given (integral) number of half-lives |
| P7.2 Power and efficiency | P7.2d: calculate energy efficiency for any energy transfer | P7.2e: describe ways to increase efficiency |
| P8 Global challenges | P8.1h: estimate the forces involved in typical situations on a public road; P8.2f: transformers and power transmission at high voltages; P8.3f and P8.3g: circular and stable orbits; P8.3h: the temperature balance of a body; P8.3i: waves used to explore the Earth’s core and deep water |
Our expert OCR GCSE Physics tutors help Foundation students work only from the plain-type outcomes OCR assesses on their papers, then add the Higher-only list if a tier change is on the table.
Several of these outcomes also carry a separate symbol, the Wingdings tick, which the specification explains as indicating content “found only in the physics separate science qualification”. That symbol is a different marker from bold type; it does not say which tier examines the outcome, and the table above relies on bold type alone.
The paper structure sets the order of work. OCR’s J249 specification says Papers 1 and 3 assess Topics P1 to P4 and P9, and Papers 2 and 4 assess Topics P5 to P8 with assumed knowledge of Topics P1 to P4 and P9. A Foundation student therefore meets motion, forces and pressure in Paper 1 first, and the magnetism outcomes that reach Foundation sit in P4.1 only.
What this changes in our programme. For J249 Foundation students the tutor plan skips the bold items entirely and spends the saved time on the plain-type neighbours: reading lines and slopes on velocity-time graphs (P2.1e), calculating with F = ma (P2.2i) and calculating efficiency (P7.2d). The same split decides what we leave for a student who later moves up a tier.
J259 uses the same device but a different layout. Its specification says: “Emboldened statements will only be assessed in Higher Tier papers.” Its outcomes are numbered within each section, such as P4.3.4, and the table reads bold from the font data, naming only the bold words where an outcome is partly bold.
| Section in J259 | Plain type (both tiers) | Bold type (Higher Tier papers only) |
|---|---|---|
| P1.1 and P1.2 Radiations and climate change | P1.1.10: radio waves produced by, or inducing, oscillations in electrical circuits; P1.2.2: the balance of incoming, absorbed and emitted radiation that sets a body’s temperature | |
| P1.3 How do waves behave? | P1.3.9: waves travel at different speeds in different substances; P1.3.10: refraction related to those speed differences | |
| P1.4 Light and sound meeting materials | P1.4.6 to P1.4.8: sound through solids, the bones of the ear, and detection and exploration by ultrasound imaging, earthquake waves and SONAR | |
| P2.1 Energy use | P2.1.8: recall and apply the efficiency equation to calculate energy efficiency for any energy transfer | only the words “describe ways to increase efficiency” in that outcome |
| P3.5 Magnetic fields | P3.5.1 to P3.5.8: poles, field patterns, compasses, induced magnets, the field around a wire and a solenoid | P3.5.9: a solenoid used to generate sound in loudspeakers and headphones |
| P3.6 How do electric motors work? | Every outcome: the motor effect, Fleming’s left-hand rule, the force equation F = BIl, and rotation of a rectangular coil | |
| P3.7 What is the process inside an electric generator? | Every outcome: induced potential difference, the moving coil microphone, alternators, dynamos and transformers, including the turns-ratio and VpIp = VsIs relationships | |
| P4.2 How can we describe motion? | P4.2.9: interpret distance-time and velocity-time graphs, including lines and slopes | P4.2.10: interpret enclosed areas in velocity-time graphs |
| P4.3 Forces and motion | P4.3.2: free body diagrams for several forces, including the balanced case; P4.3.12: recall and apply F = ma | P4.3.3: scale drawings of vector diagrams; P4.3.4: the momentum equation and collisions; P4.3.5: change in momentum = resultant force × time; P4.3.7: circular orbit at constant speed; P4.3.11: inertial mass; in P4.3.13 the word “momentum” only; in P4.3.16 the words “and estimate the forces involved in typical situations on a public road” only |
| P5.1 Radioactivity | P5.1.10: half-life and random decay; P5.1.12: interpret activity-time graphs to find the half-life | P5.1.11: net decline as a ratio after a given (integral) number of half-lives |
| P6.3 Material under stress | P6.3.2: describe the difference between elastic and plastic deformation | only the words “and use the particle model to explain” in that outcome |
| P6.4 Pressures in fluids | P6.4.1 to P6.4.6: pressure and force, gases, atmospheric pressure, pV = constant | P6.4.7 to P6.4.10: pressure in a liquid and depth, the liquid-pressure equation, upthrust on a partially submerged object, floating and sinking |
| P6.5 Big Bang models | P6.5.1 and P6.5.4: features of the solar system and its formation | P6.5.2 and P6.5.3: circular and stable orbits; P6.5.5: doing work on a gas increases its temperature |
| P7 Ideas about Science, IaS4 | the other points under outcome 3 about risks and benefits | only the words “distinguish between perceived and calculated risk” |
These differences matter to a family holding both specifications. J249 prints free-body-diagram outcomes (P2.2g and P2.2h) in bold, while J259 prints its free-body-diagram outcome (P4.3.2) in plain type. And J259 puts whole sections, P3.6 and P3.7, in bold where J249 spreads the same physics across P4.2 outcomes. Do not carry one code’s list to the other. The labels “(separate science only)” that appear beside P3.7, P1.4, P6.4 and P6.5 are a different marker from bold type and do not show which tier examines an outcome.
What this changes in our programme. For a J259 Foundation student, motors and generators are not taught as exam content, and the magnetism time goes to P3.5 fields and the plain-type circuits chapters instead. In the partly-bold outcomes the tutor teaches the plain words and leaves only the bold words for later: efficiency calculations, elastic and plastic deformation, and the momentum links in P4.3.13.
Our expert GCSE Physics tutors help Foundation students keep J249 and J259 separate, so every practice question comes from the code and tier the school has entered.
For J249, OCR’s specification says Paper 1 and Paper 3 are each worth 90 marks, are split into two sections and assess Topics P1 to P4 and P9. Section A is multiple choice worth 15 marks; Section B is worth 75 marks and includes short-answer practical, maths and structured questions and an extended six-mark Level of Response question. Papers 2 and 4 assess Topics P5 to P8 with assumed knowledge of Topics P1 to P4 and P9, and some of Section B is synoptic.
J259 is laid out differently. The specification describes a Breadth paper and a Depth paper at each tier, each worth 90 marks, and says the components “assess content from across all teaching chapters P1 to P7”. The Breadth paper has short-answer questions with no extended response; the Depth paper has at least two extended response questions, each worth 6 marks. Both codes give each Foundation paper 1 hour 45 minutes. J249 refers to 15% practical content in the written examinations, and J259 says no less than 15% of the questions will assess practical skills.
The examiners’ reports for Summer 2025 add the structural detail that the specifications leave out. The J249/01 report says its final two questions (Questions 22 and 23) overlap with the Higher paper J249/03, and the J249/02 report says its last two questions overlap with the Higher paper. The J259/01 report says its final two questions overlap with J259/03, and the J259/02 report says Questions 9 and 10 are on the Higher paper with the same mark scheme for both tiers. The J259/01 report adds that these questions tend to challenge some candidates on the Foundation paper.
What this changes in our programme. In J249 we teach P1 to P4 first and revisit them when Paper 2 content arrives, because Paper 2 assumes them. In J259 every paper can draw on the whole specification, so we cycle through the chapters rather than finish one before starting the next, and we set aside a final block for the overlap-style questions, the long-form last questions that candidates found hardest.
My son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.
We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.
I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.
These are OCR’s own published boundaries for the Foundation entries only, from the GCSE grade-boundary documents for the four June series in the tables below. The overall boundary is out of 180, the sum of the paper-level marks. OCR’s grade-boundary documents explain: “‘Grades’ at component level don’t automatically add up to the same grade at qualification level.” So the paper-level boundaries below are notional; read the overall row for the grade. Source: OCR grade boundaries.
| Series | Grade 5 | Grade 4 | Grade 3 | Grade 2 | Grade 1 | Grade 4 as % of 180 |
|---|---|---|---|---|---|---|
| June 2023 | 117 | 102 | 75 | 48 | 22 | 56.7% |
| June 2024 | 115 | 102 | 77 | 52 | 28 | 56.7% |
| June 2025 | 114 | 101 | 77 | 54 | 31 | 56.1% |
| June 2026 | 123 | 108 | 80 | 53 | 26 | 60.0% |
| Series | Paper 1 (01), grades 5 / 4 / 3 / 2 / 1 | Paper 2 (02), grades 5 / 4 / 3 / 2 / 1 |
|---|---|---|
| June 2023 | 62 / 54 / 40 / 25 / 11 | 55 / 48 / 35 / 23 / 11 |
| June 2024 | 58 / 51 / 38 / 26 / 14 | 57 / 51 / 39 / 26 / 14 |
| June 2025 | 64 / 57 / 44 / 32 / 20 | 50 / 44 / 33 / 22 / 11 |
| June 2026 | 64 / 57 / 43 / 29 / 15 | 59 / 51 / 37 / 24 / 11 |
Working: each percentage is the grade 4 mark divided by 180 and multiplied by 100, to one decimal place (102/180 = 56.7%, 101/180 = 56.1%). Across the four series the J249 grade 5 boundary ranged from 114 to 123, a spread of 9 marks, and the grade 4 boundary from 101 to 108, a spread of 7 marks.
| Series | Grade 5 | Grade 4 | Grade 3 | Grade 2 | Grade 1 | Grade 4 as % of 180 |
|---|---|---|---|---|---|---|
| June 2023 | 92 | 77 | 57 | 37 | 17 | 42.8% |
| June 2024 | 113 | 99 | 76 | 53 | 30 | 55.0% |
| June 2025 | 121 | 108 | 85 | 62 | 40 | 60.0% |
| June 2026 | 121 | 106 | 84 | 62 | 40 | 58.9% |
| Series | Breadth (01), grades 5 / 4 / 3 / 2 / 1 | Depth (02), grades 5 / 4 / 3 / 2 / 1 |
|---|---|---|
| June 2023 | 47 / 40 / 30 / 20 / 10 | 45 / 37 / 27 / 17 / 7 |

| June 2025 | 60 / 53 / 42 / 31 / 21 | 61 / 55 / 43 / 31 / 19 |
| June 2026 | 62 / 54 / 43 / 32 / 21 | 59 / 52 / 41 / 30 / 19 |
Working: 77/180 = 42.8% and 108/180 = 60.0%. J259’s grade 5 boundary was 92 in June 2023 and 121 in June 2025, a difference of 29 marks; across all four series it ranged from 92 to 121 and the grade 4 boundary from 77 to 108, a spread of 31 marks. J259 is the code where a boundary from an old series is least safe to plan against.
Our expert OCR GCSE Physics tutors help Foundation students set paper-by-paper mark targets for J249 or J259, marked against that code’s own boundary table.
What this changes in our programme. We do not give a student a single “target mark” copied from the last series. For each code the plan names a mark range from these tables, sets paper-by-paper targets inside it, and builds in a margin, because the J259 grade 5 boundary moved by 29 marks across the window. Each practice paper is marked against the code’s own table, never the other code’s.
These points come from OCR’s Summer 2025 examiners’ reports for the Foundation components of both codes. Each row pairs OCR’s observation with the step we build into sessions.
| Component and question | What the examiners’ report says | Session step |
|---|---|---|
| J249/01 Q17(a) | Confusion over the direction of the field and occasional crossing field lines were the most common errors | Draw every field with arrows on separate lines, then check no two lines cross |
| J249/01 Q19 | Some candidates confused the distance-time graph with a velocity-time graph and tried to calculate acceleration | Name the axes before choosing the equation, then say aloud what a slope means on that graph |
| J249/01 Q20(b) | A common error was to divide the original by the new lengths when calculating extension | Find extension as new length minus original length before using F = kx |
| J249/01 Q23(b) | Most could take density = mass/volume from the equation sheet; incorrect rearranging was the most common reason for a wrong final answer | Rearrange in one line, then substitute, and write each line down |
| J249/02 Q9 | Candidates across the mark range found describing the redshift of light challenging | Link redshift to wavelength in a one-sentence model answer the student can say back |
| J249/02 Q14 | Many candidates did not understand that all electromagnetic waves travel at the same speed in a vacuum | Pair the fact with wave speed = frequency × wavelength in a worked example |
| J249/02 Q19(b)(ii) | The majority incorrectly said repeating is “more accurate”; repeating enables anomalies to be identified | Practise the language of measurement: repeat to spot anomalies, then average |
| J249/02 Q20(c)(ii) | Many gave 0.51 A or 51 A; the examiners describe writing the equation from the sheet, substituting, then rearranging | Use the three-line method on every current calculation |
| J249/02 Q21(a) | Very few candidates understood the meaning of giga, G | A unit-prefix card: 1 GW = 1 × 109 W |
| J259/01 Q2(d) | Many did not convert 1500 W to 1.5 kW in a kWh calculation | Check the unit asked for before the first multiplication |
| J259/01 Q3(a)(iii) | Most candidates incorrectly selected frequency instead of period | Label a wave diagram with period, wavelength and amplitude until the three are fluent |
| J259/01 Q5(a)(ii) | Misconception: when a unit contains a power, the value is not raised to that power (0.3 cm3 is used as 0.3) | Separate the number from the unit in every substitution |
| J259/01 Q7(b) | Newton’s third law is difficult to explain | Rehearse the pair-of-forces sentence: force on the gas, equal and opposite force on the thruster |
| J259/01 Q8(a)(ii) | A common error was failing to convert 30 minutes to 1800 seconds | Convert time to seconds as the first line of working |
| J259/02 Q3(b) | Fewer candidates successfully converted the distance from cm to m | Convert all quantities before substituting, and write the converted values down |
| J259/02 Q6(a)(iv) | One of the most challenging questions: many identified outliers but gave no cause | Practise the second sentence that explains why a result is anomalous |
| J259/02 Q8(b) | The most common incorrect answer was 300,000, from patterns in the table rather than constant ÷ volume | Use pressure × volume = constant, then divide by the new volume |
Rows quote or closely paraphrase the reports for J249/01, J249/02, J259/01 and J259/02, Summer 2025. The J259/02 report also says Questions 9 and 10 are on the Higher paper too, with one mark scheme for both tiers.
Our expert GCSE Physics tutors help Foundation students prepare for J249 and J259 with equation-sheet practice, unit conversion drills and timed sets taken from the code the school has entered.
OCR’s specifications for J249 and J259 both say: “Foundation Tier assesses grades 5 to 1 and Higher Tier assesses grades 9 to 4. An allowed grade 3 may be awarded on the Higher Tier option for learners who are a small number of marks below the grade 3/4 boundary. Learners must be entered for either the Foundation Tier or the Higher Tier.” The J249 entry options are J249 F, with components 01 and 02, and J249 H, with components 03 and 04; the specification adds that a learner cannot be entered for a combination of tiers.
A student whose target is above grade 5 should be preparing for the other tier’s papers, and our Higher tier OCR GCSE Physics tutors page covers them. Entry is made by the school, so ask the school which code and tier it has entered, and when entries close, before choosing a programme. The same question applies on the other science papers; see our pages for Foundation tier OCR GCSE Chemistry tutors and Foundation tier OCR GCSE Biology tutors, and our general GCSE Physics tutoring page for the other boards.
A programme starts from the paper code, not the subject name. The tutor confirms whether the student sits J249 or J259, takes the school’s mock results or recent practice papers, and sorts every lost mark into the groups used on this page: an equation not rearranged, a unit not converted, a graph read wrongly or a long answer left unfinished. From there each session works on one group with a worked example and a short timed set.
Students also practise with OCR’s own wording. The specifications are the source for what is examined, the equation sheet is the source for the equations, and the examiners’ reports are the source for how marks were lost, so the tutor works from those documents instead of a generic revision guide. 91% of our students achieve their desired grades, and we are rated 4.8 out of 5 on Trustpilot from 59 reviews, read on 3 October 2026.
To see the official documents behind this page, use OCR’s own pages for Gateway Physics A (J249) and Twenty First Century Physics B (J259).
OCR's specification lists the entry options by code: J249 F for Gateway Physics A Foundation Tier, made up of components 01 and 02, and the Twenty First Century Physics B Foundation entry made up of J259 components 01 and 02. The school's exams officer will know which code was entered. Ask for the code before starting revision, because the Foundation papers are built differently: J249 splits the course across Paper 1 and Paper 2, while J259 sets a Breadth and a Depth paper.
Grade 5. OCR's specifications for both J249 and J259 state that Foundation Tier assesses grades 5 to 1. The same sentence says an allowed grade 3 may be awarded on the Higher Tier option, and that learners must be entered for either the Foundation Tier or the Higher Tier. A student working towards grade 6 or above is therefore preparing for the other tier's papers, which our Higher tier OCR GCSE Physics tutoring page covers.
On the June 2026 Equation Sheet for J249 01/02/03/04, OCR prints HT beside pressure due to a column of liquid (p = hρg), momentum (p = mv), force on a conductor (F = BIl) and the transformer ratio Vp/Vs = Np/Ns. On the J259 sheet it prints HT beside F = BIl, the transformer ratio, momentum, change in momentum (Δp = Ft) and pressure (p = ρgh).
Yes, and by different amounts for each code. OCR's J249 overall Foundation grade 5 boundary, out of 180, was 117 in June 2023, 115 in June 2024, 114 in June 2025 and 123 in June 2026. For J259 it was 92, 113, 121 and 121 across the same four series. Because boundaries move, our tutors set mark targets with a margin of several marks rather than aiming for the last published number.
Yes. OCR's Summer 2025 examiners' reports say the final two questions on J249/01 (Questions 22 and 23) overlap with the Higher paper J249/03, and the last two questions on J249/02 also overlap. For J259, the J259/01 report says the final two questions overlap with J259/03, and the J259/02 report says Questions 9 and 10 are also on the Higher paper, marked with the same mark scheme for both tiers.
Not as the specification prints it. In OCR's J259 specification every assessable learning outcome under P3.6 How do electric motors work? and P3.7 What is the process inside an electric generator? is in bold type, and the specification says statements in bold type will only be tested in the Higher Tier papers. P3.5 on magnetic fields continues to the Foundation papers apart from its final outcome, P3.5.9, on solenoids in loudspeakers and headphones.
Each Foundation paper is worth 90 marks and lasts 1 hour 45 minutes, for both J249 and J259. OCR's J249 specification says practical skills account for 15% of the questions in the written examinations, and the J259 specification says no less than 15% of the questions will assess practical skills. J249 Section A is 15 marks of multiple choice and Section B is 75 marks, including a six-mark Level of Response question.
