Seeing your Oxbridge admissions test in the middle of your AS mock exam week is enough to make anyone want to throw their laptop out the window. If that thought just made your heart skip a beat, take a deep breath—you’re definitely not the first person to face this.
We’ve been exactly where you are. It feels like the universe is testing your sanity, but the reality? Such a situation is one of the most common hurdles we see students navigate every single October. You won’t have to choose between your university dreams and your academic grades. You just need a strategy.
Let’s break down exactly how to manage this clash, what to say to your teachers, and how to stop the panic before it starts.
Key Takeaways
- Act Today: The faster you communicate with your school, the more options they have to help you.
- Prioritise Wisely: Your admissions test is your selection filter; your mocks are for predicted grades. Both matter, but they require different strategies.
- Schools Are Allies: Most teachers have managed this a dozen times before. Approach them as a professional, not a panicked student.
- Official Policy is on Your Side: Oxford’s special consideration policy exists precisely to handle these kinds of administrative clashes.
- Don’t “Panic-Prep”: A split-focus revision schedule beats cramming every time.
Why These Clashes Happen
The October window (typically October 12–16, 2026) is the fixed testing period for most Oxbridge admissions tests. Because schools set their own internal mock calendars independently, these two massive events often collide. It isn’t a sign that you shouldn’t apply; it’s just a logistical hurdle.
October 2026 Test Dates by Exam
| Exam | Dates |
| ESAT | Oct 12–13, 2026 |
| TARA | Oct 14, 2026 |
| TMUA | Oct 15–16, 2026 |
Which Assessment Matters Most?
Think of these as two different types of currency. One buys you an interview; the other builds your predicted grades.
| Assessment | Purpose | Strategic Priority |
| Admissions Test | Shortlisting for interview | High (The “Selection Filter”) |
| AS Mocks | Evidence for predicted grades | High (The “Foundation”) |
The Mentor’s Take: You don’t choose one. You manage both. If an exam is truly immovable, the admissions test takes priority because it is externally administered and offers no flexibility. However, because mocks are internal, they are almost always movable if you provide enough notice.
Speak to Your School Immediately
The biggest mistake? Waiting for a teacher to confirm the clash. You are the manager of your own application.
The Professional Approach
When you email your UCAS coordinator or Head of Year, don’t ask for permission to be stressed. Ask for a solution.
Email Template:
“Dear [Name],
I am writing to discuss a scheduling conflict regarding my upcoming assessments. My Oxbridge admissions test is fixed for [Date], which clashes with my [Subject] mock exam.
I am fully committed to performing well in my mocks to secure my predicted grades, and I am also aiming for a strong performance in my admissions test. Can I reschedule my mock exam to [Alternative Date] to ensure I can give both assessments my best effort?
I appreciate your support in my application process.”
Real Success Stories: It Is Manageable
- Student A (TMUA + Maths Mocks): Clashed their TMUA with AS Maths mocks. They emailed their teacher six weeks in advance; the school moved the Maths mock to the following Monday. They scored 7.8 on the TMUA and an A on their mock.
- Student B (ESAT + 3 Mocks): Had an ESAT test and two mocks on the same Tuesday. They requested to sit the mocks in the afternoon instead of the morning. The school agreed, and they both sat with a supervised lunch break.
Oxbridge Tutor Insight
“Most students waste their first three days of ‘clash anxiety’ staring at the ceiling. The best advice I can give is this: Schools are usually far more flexible when approached early. If you wait until a week before the exam, the school’s options are limited. If you tell them a month before, they can often move your entire exam hall booking. Don’t be the student who assumes the answer is ‘no.’ Be the student who starts the conversation like a professional colleague.”
Building a Revision Plan for Both
If you have to sit both within a few days of each other, use a 60/40 split. Dedicate 60% of your daily revision time to the admissions test (the selection filter) and 40% to your mock syllabus.
5 Common Mistakes to Avoid
- Waiting until the last minute: Schools hate surprises. You hate stress. Early notice solves both.
- Panic-preparing: Don’t try to cram everything in one night. You’ll burn out.
- Skipping mocks without discussion: Never just “not show up.” It makes you look like you aren’t taking your predicted grades seriously.
- Not checking your exact test date: Different subjects have different dates. Check your specific test timetable today.
- Assuming special consideration is automatic: You need to document your attempts to resolve the clash.
What If Your School Says No?
If you hit a brick wall, you have three contingency options:
- Request a Supervised Break: Ask if you can sit both exams on the same day with a strictly supervised break in between.
- Prioritise the Test: If the school refuses, focus your energy on the admissions test and inform the school that you will do your best on the mock regardless.
- Special Consideration: If the clash is severe, ask your school to contact the exam board regarding special consideration for university entrance exams.
Action Checklist
- Check your specific 2026 test dates.
- Cross-reference your mock timetable the moment it drops.
- Send the email template above to your UCAS coordinator.
- Create your 60/40 revision timetable.
- Gather any necessary documentation if your school is formal about the change.
