Year 12 and Year 13 A Level Mock Exams: Dates and the UCAS Deadline

A Year 12 A Level mock and a Year 13 A Level mock are different events, timed at different points in the two-year course, and only a Year 13 mock can reach a live UCAS application. Oxford, Cambridge and medicine, dentistry and veterinary applications close at 18:00 on 15 October; every other course follows 18:00 on 13 January. A mock timed before a student’s own deadline can still shape the prediction a school submits; one timed after cannot.

When Do Year 12 A Level Mock Exams Happen?

There is no single answer, and the spread between schools is real rather than a gap in reporting. Three sixth forms with their full current-cycle dates published show how wide it runs. St Philip Howard Sixth Form sets its Year 12 mock for 1 to 12 February. Kingsbury High School sets its Year 12 mock for 30 April to 7 May, three months later. Torquay Academy sets its Year 12 mock for the week beginning 14 June, later again — inside the same fortnight its Year 13 students begin study leave for the real exam. None of the three shares a term with either of the others.

The reason is structural rather than accidental. A Year 12 A-level course is internally assessed rather than externally examined — see our guide to the first year of A-levels for how much of the two-year specification a school is even expected to have taught by any given point — so there is no external checkpoint forcing a common date. A GCSE mock converges on a single national season because it rehearses one fixed summer exam date that every exam board shares; a Year 12 A-level mock rehearses nothing external at all. It is whatever a school’s own assessment calendar decides to call its internal check on progress, and, as the rules section below sets out, no regulator specifies a minimum number of these or when they must fall.

When Do Year 13 A Level Mock Exams Happen?

Year 13 is a tighter cluster, and it is also where some schools run the exercise twice. Torquay Academy holds its first Year 13 mock on 5 November, then a second round from the week beginning 22 February. St Philip Howard Sixth Form runs a first Year 13 mock from 2 to 16 December and a second from 1 to 12 March. Kingsbury High School runs a single round, from 25 January to 5 February. Across the three, the earliest start is 5 November and the latest finish is 12 March — a four-month window, but still far narrower than Year 12’s spread of February to June.

Year 12 and Year 13 mocks are not the same kind of event, and they do not share a calendar. A Year 12 mock is an internal checkpoint on a course with no external exam to rehearse; a Year 13 mock is timed, deliberately or not, around the one external process a Year 13 student is actually facing before results day — not the summer exam itself, but the UCAS application that has to be finished long before it.

Does It Matter Whether a Mock Falls Before or After the UCAS Deadline?

It matters more than the calendar alone suggests, because a Year 13 mock’s real function depends entirely on which side of a UCAS deadline it lands. Two deadlines apply to 2027 entry, published on UCAS’s own key dates timeline: applications to Oxford, Cambridge, and most medicine, dentistry and veterinary courses close at 18:00 on 15 October; every other undergraduate course follows the main deadline, 18:00 on 13 January. A mock sat before a student’s own date is still live evidence a school can draw on for the prediction it submits with that application. A mock sat after it plays no role in that application at all — the reference has already gone, and the only levers left are the real exam and whatever classwork arrives in between.

The three schools above show exactly how this plays out. None of them schedules its first Year 13 mock before 15 October, so none offers an Oxbridge, medicine, dentistry or veterinary applicant a mock result ahead of that specific deadline — the October date has already passed before any of these three schools has sat one. Torquay’s 5 November mock and St Philip Howard’s 2–16 December mock both fall after 15 October but before 13 January, so they can still inform a prediction for the main-deadline courses most applicants are applying to. Kingsbury’s single window, 25 January to 5 February, falls after both deadlines — for a Kingsbury Year 13 applying to any 2027-entry course, this cycle’s Year 13 mock cannot feed either prediction; the application, whichever deadline it followed, has already been sent. Second-round mocks — Torquay’s from 22 February, St Philip Howard’s from 1 to 12 March — fall after both deadlines everywhere, which is exactly why they read less like an application input and more like exam practice for the summer.

This is not a logic that only shows up in a school’s own calendar. One private mock-exam provider, Ark Education, states its own commercial cut-off in exactly these terms: mocks should be complete “by 30 November so predictions and references can be prepared” for the January deadline. What that provider does for a paying customer booking a slot, a family working from a school’s own published calendar has to work out for themselves — and the calculation is the same one either way: find the deadline, find the mock, and see which side of it the date falls on. For the mechanics of how a mock result actually becomes a number on a UCAS form, see our full guide to how predicted grades are set.

How Much of the A Level Course Does a Mock Actually Cover?

Timing also decides how much of the specification a mock can test. A February-timed Year 12 mock, of the kind St Philip Howard sets, falls when perhaps half of the two-year course has been taught — Year 12 content is internally assessed rather than externally examined, and a school is not required to have covered any fixed proportion of the specification by a set date (our guide to the first year of A-levels covers this in full). A June-timed Year 12 mock, of the kind Torquay Academy sets, catches most of what remains of the first year, but nothing at all from the second.

A Year 13 mock, sat once the great majority of the two-year course has actually been taught, comes far closer to sampling what the real summer papers will ask. That is also the practical reason a Year 13 result, not a Year 12 one, is the evidence a school leans on hardest when it puts a prediction together — not because a Year 12 mock is worthless, but because it can only ever speak to the part of the course a student has met so far.

Do Year 12 Mocks Feed Into a UCAS Predicted Grade at All?

Yes, indirectly, but a Year 12 mock is never itself submitted anywhere. UCAS receives one predicted grade per subject, decided by the school — our full guide to how predicted grades are set covers exactly how that number is arrived at and what UCAS requires of the process. What a Year 12 mock does is arrive early enough to become part of the evidence a school is already holding well before any Year 13 mock, application or deadline exists. Our guide to the first year of A-levels puts it plainly: the predicted grades on a UCAS application draw heavily on Year 12 performance, mock results among them, gathered months before a student has even chosen where to apply.

The first mock result that can appear inside a live application, in the sense of directly informing the prediction that goes with it, is a Year 13 one — and only when it lands ahead of the student’s own deadline, exactly as the previous section set out. A Year 12 mock is preparation for that evidence base, not a contributor to a specific submitted number.

What Rules Actually Govern an A Level Mock?

Fewer than most parents expect, and the one rule that does exist is often misattributed. Ofqual’s resilience guidance — “for centres delivering GCSE, AS and A levels, Project Qualifications and the Advanced Extension Award in maths (AEA) to provide resilience in the exam system in the unlikely event that government determines that exams are not able to go ahead” — asks schools to hold students to exam conditions in at least one mock and to keep the papers, so there is fallback evidence if a summer series is ever cancelled nationally. Ofqual is explicit that “one set of mocks for this purpose should be sufficient.”

What Ofqual does not do is set a minimum or maximum number of A-level mock sittings. Its own consultation record is direct about this: the guidance “was clear that teachers should guard against over-assessment and did not outline the number of assessment opportunities that should be in place.” That is the regulatory half of the spread described above — a school running two Year 13 mock rounds and a school running a single round are both fully within the rules, because there is no rule fixing the count. What decides a school’s own calendar is its own assessment policy, not a JCQ or Ofqual timetable.

What If My Child Is Ill or Misses an A Level Mock?

The formal process that exists for this governs the real exam, not the mock. The Joint Council for Qualifications sets out two separate provisions, and mixing them up is the most common way a parent ends up briefed on the wrong one.

A student who sits an A-level paper but is unwell at the time can be considered for special consideration under JCQ’s rules for candidates “present for the assessment but disadvantaged” — a mark addition to the affected component, capped at 5% and reserved “for the most exceptional cases” such as terminal illness; ordinary illness on the day of the exam sits in the far more commonly used 2% band. A student who misses an A-level component entirely has to clear a different bar: JCQ’s minimum requirement for “GCE AS and A-level qualifications (AQA, OCR, Pearson and WJEC specifications)” is that “one whole component, which is a minimum of 15% of the total assessment, must have been completed” before any award can be made at all. JCQ’s own worked example makes the boundary concrete: a candidate who sits one A-level paper worth over 15% of the total assessment but then misses a second exam through illness “meets the minimum requirements” for that subject’s award; a candidate who misses every paper does not.

None of this applies to a school’s own internal mock. JCQ’s guide covers the summer exam a student is entered for with an awarding body — it says nothing about mocks at all, because a mock has no formal special consideration process of its own. If a child is too unwell to sit one, the usual outcome is simply that the school notes it and moves on; the real exam later in the year is where this JCQ process, and its 15% floor, actually applies.

What Should You Actually Do With a Disappointing A Level Mock Result?

What a disappointing mock actually means depends on exactly the calendar logic set out above, and it is worth being specific rather than reassuring in the abstract.

A Year 12 result has a full year ahead of it before any UCAS application exists at all — there is time to close a gap in the specification’s first half before the course, or the process that turns it into a prediction, moves on. A Year 13 result that lands before a student’s own deadline is different: it is one of the last pieces of evidence a school will have before deciding what to submit, so it is worth treating as a genuine prompt to focus revision on the specific gaps it shows, not a verdict. A Year 13 result that lands after the deadline has already been sent changes what is actually left to influence — not the prediction, which has gone, but the one thing that still counts on results day: the real exam itself.

That last case is also where the stakes are highest and the runway shortest. A tutor working from the specific gaps a mock has just shown — not a generic revision plan — is the most direct way to turn a poor result into a different outcome by the summer series. Once results are actually in, our guide to revising for A-levels effectively sets out what the evidence says works between now and the real exam.
