Predicted Grades & UCAS

How to Improve Your A-Level Predicted Grades Before UCAS

Dr Waleed Ahmad, MBBS9 min read

Quick answer

You can improve your A-level predicted grades, but only before your school submits your UCAS application, and only with evidence. Teachers raise predictions when they see better marks in mocks and assessments, consistently strong classwork, and a proper plan. That evidence takes 6 to 10 weeks to build. The students who pull it off start in the summer, not in October.

Every autumn I speak to students who have just found out their predicted grades, and they're gutted. A BBB prediction when they need AAB. A teacher who played it safe. A UCAS application that suddenly can't carry the universities they actually want. Here's the good news: a predicted grade isn't a verdict. It's a judgement based on evidence, and evidence can change. The bad news? Almost every student who tries to change it starts too late.

Key takeaways

  • Your teachers set your predicted grades, usually in September or October of Year 13, based mostly on your end of Year 12 exams.
  • They can be changed any time before your school submits your UCAS application. After that, they're locked.
  • Teachers need evidence to raise a prediction. Better mock results, resat assessments, consistent classwork. Not promises.
  • Realistically you've the summer holiday plus the first half term of Year 13 to build that evidence.
  • Applying for medicine, dentistry or Oxbridge? The deadline is mid-October, so your evidence needs to exist by early October.

What predicted grades actually are, and who decides them

A predicted grade is your teacher's professional judgement of the grade you're most likely to get in your final exams. It goes on your UCAS application, and universities use it, alongside your GCSEs and personal statement, to decide whether to make you an offer.

Now, teachers don't pluck these numbers out of thin air. In most schools the prediction comes from:

Look at that list again. Every single thing on it is written, marked, dated evidence. That matters, because it tells you exactly what you need to produce if you want the number to move.

Yes, predicted grades can be changed. Here's the deadline that matters

The most common myth I hear is that predictions are final once they're set. They aren't. Your school can revise a predicted grade at any point up until your UCAS application is submitted. After submission, they're fixed for that cycle.

That creates two very different timelines depending on what you're applying for:

The trap almost everyone falls into

Students hear their predictions in September, feel deflated for a fortnight, and only start acting in mid-October. By then the school's internal deadlines have passed or the application has already gone in. The students who actually move a prediction decided to act before the predictions were even published. They walked into September with better evidence than they left Year 12 with.

What actually convinces a teacher to raise a prediction

Put yourself in your teacher's shoes for a second. Their predictions get tracked. If they predict you an A and you get a C, that reflects on them and on the school's credibility with universities. So "I'll work really hard this year, I promise" moves nothing. These four things do:

  1. A better mark in a formal assessment. This is the gold standard. If your school runs September or October assessments, or lets you resit a Year 12 paper, jumping from a C to an A on real exam questions is almost impossible to ignore.
  2. A resit of the exam that caused the low prediction. Many schools will let you resit end of Year 12 papers early in the autumn term if you ask. Most students never ask.
  3. A visible run of strong classwork. Four to six weeks of consistently excellent homework and test scores builds the trajectory argument: that your Year 12 result was the old you.
  4. A proper plan. Teachers take you more seriously when they can see structure. A real revision timetable, targeted work on your weak topics, extra support in place. It tells them the improvement will continue rather than being a one-off.

The 8-week plan to raise a predicted grade

This is the sequence I walk our students through. It assumes you're starting in the summer or the first days of September. Starting later? Compress it, but the order stays the same.

Weeks 2 to 6: Build the evidence

Weeks 6 to 8: Turn the evidence into a new prediction

If your prediction still won't move

Sometimes a teacher won't budge, even with decent evidence. You still have options:

The uncomfortable truth about predicted grades

When I was doing my A-levels, I noticed something that has been confirmed to me a hundred times since I started teaching. The students with the strongest predictions weren't usually the cleverest in the room. They were the ones who treated Year 12 exams and the first term of Year 13 as the real thing, while everyone else saved their effort for "the exams that count".

By the time most students start working seriously, the two numbers that shape their university options have already been written down: their GCSE results and their predicted grades. If you're reading this in the summer or early autumn, you're in the last window where that second number is still yours to change. Use it.

Frequently asked questions

Can predicted grades be changed after they're set?

Yes. Right up until your school submits your UCAS application, your teachers can revise your predicted grades. Once the application goes off to UCAS, they're locked for that cycle. So the window between September and your submission date really matters. It's your last chance to show new evidence.

Do universities ever accept students who miss their predicted grades?

Often, yes. Universities make offers based on predictions but confirm places based on your actual results, and plenty of them show flexibility if you narrowly miss, especially if you did well in the subjects that matter for the course. But relying on that's a gamble. You're in a much stronger position with a prediction that reflects what you can actually do.

When are A-level predicted grades decided?

Most schools set predicted grades early in the autumn term of Year 13, usually September to October. They lean heavily on your end of Year 12 exams and your first few weeks back. Some schools finalise them as late as their internal UCAS deadline, which buys you a few extra weeks to show evidence.

Can I ask my teacher directly to raise my predicted grade?

You can, and you should. But bring evidence, not enthusiasm. Something like "I want to be predicted an A. What would you need to see from me by October?" turns your teacher into an ally and gives you a concrete target. Teachers respond to marked work, mock results and consistent classwork. They don't respond to promises.

Do predicted grades matter for medicine and Oxbridge?

Massively. Medicine, dentistry, veterinary science and Oxbridge applications go in by the mid-October deadline, and most medical schools screen applicants against minimum predicted grades (typically AAA) before they even read the rest of the application. One grade on a prediction can decide whether your application gets looked at.
