Four A-levels, the IB and CBSE are all taught in Dubai, and they are not the same chemistry. Here is what each one names — and what Oxford and Cambridge do with that.
Get the Organic Chemistry pack — £180Four different chemistry A-levels are taught in Dubai, alongside the IB and CBSE. Oxford Chemistry requires no admissions test for 2027 entry; Cambridge Natural Sciences requires the ESAT of everyone. Oxford interviews Chemistry first between 7 and 10 December 2026 — inside the last school week before KHDA closes Dubai private schools on 14 December.
Oxford’s Chemistry department publishes the criteria its selectors use, and one of them is an understanding of the chemical concepts covered in courses taken so far. It goes further, and says that selectors assess each candidate taking into account the educational background of students and the level of their existing knowledge and experience. Cambridge says something close for Natural Sciences: it advises applying in the Physical Sciences stream if you have studied Physics and Maths A levels, because your interview will be on subjects that you have already studied, and states plainly that your choice of stream and your current courses will affect the types of questions that are asked at interview.
Neither university is guessing what you have been taught. Both have told you they will work it out and interview you against it. Which means the first useful question for a chemistry applicant in Dubai is not what Oxbridge interviews are like in general — it is which chemistry your school actually taught you, because in Dubai that is genuinely uncertain.
The British curriculum is the largest single curriculum in Dubai’s private schools, with 144,307 pupils on KHDA’s own 2024/25 figures, and the Indian curriculum is the next largest at 25.7 per cent. But a British-curriculum school in the UAE may enter students for any of four different chemistry specifications, and which one is not published for the market as a whole. This page reads all four, plus CBSE, against each other, and then sets the answer against Oxford’s and Cambridge’s own published arrangements for December 2026.
If you have read our pages on Oxbridge maths interviews from Dubai or engineering from Dubai, you already know the shape of the problem there. A Dubai student can complete A-level Mathematics having met no mechanics at all, because the international boards let you choose which applied papers to sit. That is a real, documented route gap, and it belongs to the exam board rather than to the country.
It does not transfer to chemistry. We checked all four specifications’ own structure sections rather than assuming either way, and the answer is clean.
| Specification | Optional content? | Hybridisation and orbital overlap | DNA and enzymes | Something it alone names |
|---|---|---|---|---|
| Cambridge International 9701 | None — three routes differ only in when papers are sat | Yes, both | Neither; stops at di- and tripeptides | Electrophoresis of amino acids and dipeptides |
| Pearson Edexcel International A Level | None — all six units required | No; orbital shapes only | Neither; stops at proteins | Defines an orbital as a region holding two electrons of opposite spin |
| OxfordAQA 9620 | None — final unit assessed on all content | No | DNA only through cisplatin; enzymes not named | Epoxyethane; Period 3 chlorides as well as oxides |
| AQA, the UK A-level | None — third paper assessed on any content | No | Both, as named sub-topics | Ozone depletion; alcohol production |

Our UAE physics page reached the same structural answer for the three physics specifications, by its own separate evidence, and found the same thing we did: the interesting differences are not omissions but additions. That finding now holds across two subjects, which makes it a property of how science A-levels are built rather than a quirk of one syllabus.
So the question to ask about your own route is not what it left out. It is what it gave you that the others did not, and what it assumed you would meet later.
Practise past the edge of your specification — Organic Chemistry, £180
Ten of our own practice questions in the style of the interview, written by specialist subject tutors — SN1 against SN2, resonance and chirality, atomic orbital nodes and rate laws, each taken through to a full worked answer, with prompts you can try first.
Get the Organic Chemistry pack — £180Bonding through orbitals, and it is alone in this. Cambridge International 9701 asks candidates to describe covalent bonds in terms of orbital overlap giving sigma and pi bonds, spelling out that sigma bonds form by direct overlap between the bonding atoms and pi bonds by the sideways overlap of adjacent p orbitals above and below the sigma bond. The next learning outcome in the same section asks students to use the concept of hybridisation to describe sp, sp2 and sp3 orbitals. Earlier, in its atomic structure topic, it asks them to describe and sketch the shapes of s and p orbitals.
Set that against the other three. AQA’s UK specification devotes one short section to the nature of covalent bonds, and the whole of it reads: a single covalent bond contains a shared pair of electrons, multiple bonds contain multiple pairs, a co-ordinate bond has both electrons supplied by one atom, and students should be able to draw a covalent bond as a line and a co-ordinate bond as an arrow. OxfordAQA carries that section word for word. Neither document contains the word hybrid anywhere.
Pearson sits in between. It defines an orbital as a region within an atom that can hold up to two electrons with opposite spins and asks students to describe the shapes of s and p orbitals — but its atomic structure topic runs from there straight to electronic configuration and never reaches hybridisation, sigma bonds or pi bonds.
This matters more than it looks. Orbital overlap is exactly the kind of thing an Oxford Chemistry tutor reaches for when a candidate has answered the surface of a question and there is time left. If you sat 9701, you have met it and should be ready to be pushed on it. If you sat OxfordAQA, Pearson or the UK AQA specification, you have not, and an interviewer who has read your school’s curriculum may or may not know that.
Here the split runs the other way, and the UK specification is the outlier.
If you are applying for Cambridge Natural Sciences with a biological leaning, or to Oxford Chemistry with biochemistry on your personal statement, that difference is worth knowing about yourself before December. The same pattern of small, named divergences runs through the rest of the organic content: OxfordAQA adds epoxyethane to its alkenes topic and extends Period 3 chemistry to the chlorides as well as the oxides, while dropping the ozone depletion and alcohol production sub-topics the UK specification carries.
The honest answer is that the syllabus document cannot tell you, and it is worth being precise about why rather than guessing in either direction.
A 2027-entry applicant sat Class XI under the 2025-26 curriculum and sits Class XII under the 2026-27 one. Those two documents are written at different levels of detail. The 2025-26 edition enumerated learning outcomes: its Electrochemistry unit named standard electrode potential, the Nernst equation and its application to chemical cells and the relation between Gibbs energy change and EMF of a cell; its Kinetics unit named order and molecularity of a reaction, rate law and specific rate constant and the Arrhenius equation; its Coordination Compounds unit named Werner’s theory, VBT, and CFT.
The 2026-27 edition gives NCERT chapter headings instead. Its whole Electrochemistry unit reads: Electrochemical Cells, Galvanic Cells, Nernst Equation, Conductance of Electrolytic solutions, Electrolytic Cells and Electrolysis, Batteries, Fuel Cells, Corrosion. The phrase electrode potential does not occur in the document. Its whole Kinetics unit reads: Rate of a Chemical reaction, factors influencing rate of reaction, integrated rate equations, Temperature Dependence of the rate of a reaction, Collision theory of Chemical Reactions. Neither the rate law nor Arrhenius is named. Its Coordination Compounds unit says Bonding in coordination compounds where the previous edition said VBT and CFT.
You cannot state the Nernst equation without a standard electrode potential, and temperature dependence of rate is where the Arrhenius equation lives. So this is a change in how the document is written, not evidence that the chemistry has gone. What it does mean is practical: a syllabus that lists chapter headings cannot be audited against an interviewer’s assumptions the way an itemised specification can. A tutor can take Cambridge International 9701 line by line and tell a candidate exactly what they have and have not met. With the 2026-27 CBSE document that is not possible, and anyone who tells you otherwise is reading the older edition.
Where CBSE and the A-levels part company — Inorganic Chemistry, £180
VSEPR on ClF3 and IF7, hydrogen bonding down Groups 16 and 17, and benzene’s bonding set against borazine’s — ten questions written by specialist subject tutors, with prompts and a worked answer each, on exactly the inorganic ground the CBSE unit list does not name.
Get the Inorganic Chemistry pack — £180Two things are worth saying in the candidate’s favour, both from the Class XI year this cohort actually sat.
The first is molecular orbital theory. The Class XI chemical bonding unit names VSEPR theory, the concept of hybridization, involving s, p and d orbitals, and molecular orbital theory of homonuclear diatomic molecules. Not one of the four A-level chemistry specifications teaches molecular orbital theory, and only Cambridge International teaches hybridisation. The second is that the same year names buffer solutions and the Henderson Equation, entropy as a state function and Gibbs energy change for spontaneous and non-spontaneous processes, and — in the hydrocarbons unit — the free radical mechanism of halogenation, the mechanism of electrophilic addition and, for benzene, the mechanism of electrophilic substitution. The widespread assumption that a CBSE student arrives with less chemistry does not survive contact with that list.
Where the CBSE documents do visibly stop is in three places, and each is provable from the unit list itself rather than from a keyword search.
For the IB there is a route fact worth planning around, and it comes from Oxford Chemistry’s own page rather than from us. Its IB requirement is 40 points including core points — but the shape of the Higher Level grades changes with your mathematics. An applicant offering HL Mathematics needs 766 at HL, with 7 in HL Chemistry and 6 in HL Mathematics. An applicant offering SL Mathematics needs 776 at HL, with 7 in both HL Chemistry and a second HL science subject, and 7 in SL Mathematics: Analysis and Approaches. In other words, taking Maths at Standard Level does not simply lower the bar elsewhere; it raises the requirement on a second science. If you are choosing subjects now, that is the sentence to read twice.
We make no claim on this page about what IB Higher Level Chemistry does or does not teach, because we were not able to reach the IB’s own subject documentation to check it, and we are not going to compare a syllabus we have not read. Read your own subject guide.
For the Ministry of Education curriculum the question is settled earlier than the interview. Oxford lists the Tawjihiyya as Not accepted, so an applicant holding it alone is not eligible on that certificate and needs A-levels, the IB or Advanced Placement first. Our Oxbridge interviews from Dubai and the UAE page covers that ground, along with the College formats and the country’s admissions statistics.
No, and it is worth being able to say so with the document in hand, because several guides still imply otherwise. UAT-UK publishes a closed list for 2027 entry of the Oxford courses for which, in its words, either the ESAT, TARA or the TMUA is compulsory. We read all five pages of the Oxford section. It runs from Biomedical Sciences through fourteen engineering codes, Physics and Physics and Philosophy, ten courses requiring the TARA and five requiring the TMUA, ending with Mathematics and Statistics, after which the list moves to another university. Chemistry has no row. In fact the word Chemistry appears exactly once in those five pages, as one of the ESAT module options a Biomedical Sciences candidate may choose.
Oxford’s Chemistry department corroborates it from the other side. It lists the evidence its selectors use as the UCAS application including references and personal statement, examination results, and the interview. No test appears. It also guarantees something useful: shortlisting is done so as to guarantee that all shortlisted applicants receive at least two interviews. Its standard conditional offer is A*A*A with three A-levels that must include Chemistry and Mathematics, both A* grades in science or maths subjects.
Cambridge is a different arrangement, because chemistry there is not a degree but a subject inside Natural Sciences. All applicants for Natural Sciences are required to take the Engineering and Science Admissions Test, at an authorised assessment centre, with advance registration. The modules are Mathematics 1 plus any two chosen from Biology, Chemistry, Physics and Mathematics 2 — so it is entirely possible to sit the ESAT for Natural Sciences without taking its chemistry module, and to be interviewed on chemistry all the same. In the first year you choose three science subjects from seven areas, of which Chemistry is one. The 2025 cycle ran at five applications per place with 576 accepted; for applicants from the UAE across all Cambridge courses that year, 130 applications produced 9 offers and 8 acceptances, a 6.2 per cent success rate. Our guide to Oxbridge interviews from overseas sets that in context.
Oxford publishes Chemistry’s timetable by name. First college interviews run between Monday 7 December and Thursday 10 December 2026. Decisions about second college interviews are communicated by 11am on Monday 14 December, and second college interviews take place on Tuesday 15 and Wednesday 16 December.
KHDA sets the start of the winter break for Dubai private schools at 14 December 2026, and its calendar marks that row All schools — September-start and April-start alike. Put the two together and Chemistry sits differently from its neighbours. Oxford says of Medicine that each shortlisted candidate will be interviewed by two colleges, with the interviews being either on Monday 14 or on Tuesday 15 December, and of Mathematics that most first and second college interviews will take place on Monday 14, Tuesday 15, Wednesday 16 and Thursday 17 December, although interviews for some colleges may start in the week commencing Monday 7 December. Both of those land mainly in the first days of the Dubai break. Chemistry is the other way round: its first interviews fall in the last working week of term, while you are still at school, and only its second interviews fall in the break. If your school runs end-of-term events in that week, the clash is with the first round, not the second. And because Oxford can call additional interviews at short notice, treat any published window as the earliest part of the story rather than the whole of it.
The clock is the easy part. The IANA time zone database gives Asia/Dubai a single standard offset of four hours with no seasonal rule, so nothing shifts in December. A 09:00 to 17:00 UK interview day is 13:00 to 21:00 in Dubai, and that 11am UK decision deadline lands at 15:00 local. This is one of the kinder time zones in the overseas field — no small-hours interviews, and a decision that arrives in the afternoon rather than overnight.
Two scope notes. The 14 December date is Dubai, set by KHDA; Abu Dhabi schools work to ADEK’s calendar and we have not verified a break date there, so do not carry this one across. And the Ministry of Education’s December examination weeks bind schools following the Ministry curriculum, not British, IB, American or Indian-curriculum schools in Dubai, which KHDA binds to the break dates only.
The repair list depends on your route, which is the whole point of this page. Every item below is something one specification names and another does not.
One thing no one can sell you is the questions themselves. Nobody outside the Colleges has the real questions, and any service claiming to is not telling you the truth. What written practice can do is put unfamiliar problems in front of you, with the reasoning written out, so the first time you have to think aloud under pressure is not in December.

Four specifications are in use across the market: AQA’s UK A-level Chemistry, Cambridge International 9701, Pearson Edexcel International A Level Chemistry and OxfordAQA 9620. Cambridge accepts all three international boards, saying it accepts international A levels offered by Cambridge International, Oxford AQA or Pearson Edexcel, as they are comparable to UK AS and A levels. Eligibility is therefore settled; what you were taught is not. The answer is printed on your exam entry and on the specification your teachers work from.
No, and this is the single most useful thing on this page. In A-level Maths a Dubai student can finish the qualification having met no mechanics at all, because both international boards let you choose which applied papers to sit. No chemistry specification works that way. Cambridge International 9701 publishes three routes and they differ only in when papers are sat, never in what is covered. Pearson states that students wishing to take the International Advanced Level must, therefore, complete all six units, and that as a minimum, all the topics in the content must be taught. OxfordAQA ends with a unit assessed on all content. AQA’s Paper 3 is assessed on any content. There is no chemistry route that leaves something out.
Bonding through orbitals. Cambridge International 9701 asks candidates to describe covalent bonds in terms of orbital overlap giving sigma and pi bonds, and then to use the concept of hybridisation to describe sp, sp2 and sp3 orbitals. Neither AQA’s UK specification nor OxfordAQA goes near this: both define a covalent bond as a shared pair of electrons and stop there, and the word hybrid does not appear in either document. Pearson gets closer, defining an orbital as a region within an atom that can hold up to two electrons with opposite spins and asking students to describe the shapes of s and p orbitals, but it never reaches hybridisation or sigma and pi bonds either.
Only AQA’s UK A-level, of the four. Its organic content list carries a section titled Amino acids, proteins and DNA, with Enzymes and DNA as sub-topics in their own right. OxfordAQA’s nearest section is titled Amino acids and proteins, the word enzyme does not appear anywhere in the specification, and its only DNA learning outcome asks students to explain why cisplatin prevents DNA replication. Pearson’s organic nitrogen topic is Amines, Amides, Amino Acids and Proteins and none of its topics names nucleic acids. Cambridge International stops at the formation of amide bonds between amino acids to give di- and tripeptides, then adds electrophoresis, which none of the other three teaches.
That is not a question the syllabus document can answer, and it is worth being exact about why. A 2027-entry applicant sat Class XI under the 2025-26 curriculum and sits Class XII under the 2026-27 one, and the two are written differently. The 2025-26 edition printed learning outcomes in terms: standard electrode potential, the Nernst equation, the relation between Gibbs energy change and EMF of a cell, rate law and specific rate constant, the Arrhenius equation, Werner’s theory, VBT, and CFT. The 2026-27 edition gives NCERT chapter headings instead, so its Electrochemistry unit names the Nernst Equation but never uses the phrase electrode potential, and its Kinetics unit names integrated rate equations but neither the rate law nor Arrhenius. A syllabus that lists chapter headings cannot be audited against an interviewer’s assumptions the way an itemised specification can. It does not follow that the chemistry is absent, and this page does not claim that.
Molecular orbital theory. The Class XI unit on chemical bonding names VSEPR theory, the concept of hybridisation involving s, p and d orbitals, and molecular orbital theory of homonuclear diatomic molecules. No A-level chemistry specification read for this page teaches molecular orbital theory at all, and only Cambridge International teaches hybridisation. The same Class XI year also names buffer solutions and the Henderson Equation, entropy as a state function and Gibbs energy change, and the mechanism of electrophilic addition. A CBSE candidate arrives with bonding models an interviewer may not expect them to have met.
No. UAT-UK publishes the closed list of Oxford courses for which, in its own words, either the ESAT, TARA or the TMUA is compulsory. Chemistry is not on it. Across the five pages of that list covering Oxford, the word Chemistry appears exactly once, as an ESAT module option under Biomedical Sciences, and neither Oxford Chemistry course code appears anywhere in the document. Oxford’s own Chemistry department page says the same thing from the other direction: the three things selectors assess on are the UCAS application, examination results and the interview. Cambridge is different, because chemistry there sits inside Natural Sciences, and all applicants for Natural Sciences are required to take the Engineering and Science Admissions Test.
Oxford holds first college interviews for Chemistry between Monday 7 December and Thursday 10 December 2026, communicates second college decisions by 11am on Monday 14 December, and holds second college interviews on Tuesday 15 and Wednesday 16 December. KHDA starts the winter break for every Dubai private school on 14 December 2026. So Chemistry is the course whose first interviews fall inside the last week of term, where Oxford puts Medicine on either Monday 14 or Tuesday 15 December and most Mathematics interviews across 14 to 17 December, adding that some Mathematics colleges may start in the week commencing Monday 7 December. Dubai is four hours ahead of the UK in December, which puts a 09:00 to 17:00 UK interview day at 13:00 to 21:00 locally and that 11am decision deadline at 15:00. Abu Dhabi sets its own calendar and this date does not apply there.
