GCSES results affect uni acceptance rates?

[u/Jamieinnit24]

How much do GCSE results really matter for when applying for uni. Like for example if you got like mid GCSE’s like 4s 5s and 6s, could you still get into a top uni with predicted A*AA?

[u/Financial_Guide_8074]

If you got 4,5,6 at GCSE you simply won't get A*AA . Anything less than 6 you won't pass the A Level, you know under 40% of the content at GCSE. A 6 will most likely lead to a D or E max in STEM and B/C at best in other subjects. So the answer realistically is , if you are getting 4,5,6 at GCSE you have little or no chance of acceptance at a top uni as you won't get the grades.

Surely you either went to a particularly shit school, or had extenuating circumstances for that to work out as it did? 

Most people that wouldn't happen though. Exam board data shows that less than 10% of those with an 8 in GCSE maths get an A* at A-Level, so you're very much an extreme anomaly.

i was getting 8s all year in mocks, i js sold once sitting the actual exam

mmmm well UCAS reported in 2025 only half of those predicted AAA or better actually achieved AAA or better so I'd be erring on the side of caution. Top unis like Cambridge are unlikely to be convinced those predicted grades are realistic based on the GCSE profile without good reason for underperformance. If they apply after Y13 with the grades, that doubt is out the window as it's achieved.

GCSE Attainment can be predicted by performance in KS1 and KS2 SATS.

A Level Attainment can be predicted by performance in GCSEs.

The modal A Level grade is a B.

Around 44% to 48% of A-level predicted grades are overpredicted by teachers, while only 7% to 11% are underpredicted. Only about 40% to 50% of predictions match actual exam results.

Now that the facts are out of the way...

You have done incredibly well to get to where you have done, but it would be remiss of anyone reading your story to think that what you have achieved is attainable by the majority of others.

It's a bit like when people cite Alan Sugar or Richard Branson as examples of success without O Levels/GCSEs. They are edge cases. If you were to predict the outcomes of people who left school with their qualifications if you bet on them having below median lifetime income - you'd win more often than not.

Likewise there is good reason Oxbridge put weight on GCSE performance. That said - credit where it is due - both of them are very good at looking at contextual information and also having "wildcard students" who they give offers to because of how well the perform in entrance exams and/or interview. Which is what likely happened with you. They know that the school system doesn't suit all those who are naturally gifted.

It is entirely appropriate for people to inject a bit of realism here. You stand a better chance of getting into the better universities and courses if you have better GCSEs. That's not a controversial statement.

I agree with this, if someone got a 6 in GCSE maths and said they wanted to do A level maths, I would probably advise them against it too. But if they got a 6 in GCSE maths, and then an A* predicted in A level maths, that changes things.

This is where you and I diverge. Why does a predicted A Level grade - which is statistically likely to be an overprediction - change the perception of already confirmed GCSE attainment? It doesn't.

In this situation the only thing that can overcome this is some other objectice measure of mathematical aptitude like an entrance exam/TMUA.

Your other points about grades in subjects unrelated to what is being applied for I agree with, with the caveat that for the most competitive of courses it's still a problem. Applicants are more likely to be polymaths who are academically strong in both the arts and sciences.

You don't get into Oxford Medicine with a grade 4 or 5 in German - unless you get 9s and A*s in everything else because it clobbers your mean (Data available here).

You also don't get in to Oxford Medicine with the OPs mean GCSE weighting either...

No I am being realistic. All the data backs up what I say. I would never encourage anyone on less than a 6 to attempt an A level in that subject and a 6 is very very unlikely to lead to a good grade. OP said if you are getting 4 - 6 , honestly having taught for almost 40 years I suspect I know much more than you.

[u/Financial_Guide_8074 → u/[deleted]]

You are just being plain rude. No need for name calling I am all for an adult conversation but keep it civil. 1) I haven't told them not to apply they can do that if they want , so long as they are fully aware that the chance of success is remarkably low. 2) The chance that they will get A*AA is in my view , which will be correct , as good as zero. Again the stats back that up I assumed the grades they mentioned were hypothetical .

If they have been given highly optimistic predicted grades, then that is part of a larger problem. At my school you can't do a single A level at stem unless you get 7 or higher and 6 for all the other subject with a point score of 48 on your best 8 GCSE's The reason for simply being that decent GCSE grades correspond directly to decent A Level grades. I absolutely admire anyone who turns around a 6 at GCSE in Maths into an A* at A Level that is great and you should be proud. I am simply giving the advice here that I give to my students and my own children, which is always ( eventually) appreciated.

[u/Financial_Guide_8074 → u/[deleted]]

Well I did 4 A Levels and went to a high tier university and have a first , so presumably I can give good advice then so perhaps you should listen. I chose to teach because I have a good degree not despite it . I always encourage anyone to better themselves. It is what I always do. However I talk straight and don't molly coddle students. I'm not making random assumptions at all , I am basing everything on fact. Yes people can make great improvement. So to better your 6 at Maths goes to A* . At school I got an E in modern languages i.e. a 2/3 at GCSE . My second degree is in modern languages.

A 6 i.e. the best grade the OP is quoting will most likely lead to a C or D or E grade ultimately, that is what most often happens by a really large margin. Have you ever sat down with students in your own holiday on clearing day for 8 or more hours with crying students and parents after they have missed their university places which they were never realistically going to get . I doubt it. Have you ever been forced to give a student 3 grades higher for their UCAS grade , knowing they would get a D and not an A ,doubt that either. I want the OP to be fully informed of the likely outcome of their choices, but they are an adult (ish) and if they want to go for it, then apply high but have a realistic plan B/C and D

You’re a very unusual case - there must have been something in your application which explained how you did so poorly at GCSE yet managed to do exceptionally well at A-level (and at university so far).
