It's useful to understand that your GCSE results won't completely define your future. That said, they can certainly have an impact. Anything from getting into your preferred sixth form through to making it in your chosen career might be affected by the grades you pick up at the end of year 11. Let's take a closer look at what you should know about GCSEs.
What are GCSEs?
GCSEs (General Certificate of Secondary Education) are subject-based academic qualifications that students study across year 10 and 11 at secondary school in England and Wales.
The grading scale is from 9-1, with 9 being the highest grade.
How will GCSEs affect my future studies?
1. GCSEs can determine the sixth form you go to
Entry requirements for school and college sixth forms vary. It's pretty common to see colleges ask for five GCSEs at grade 4 or better, with some courses maybe needing you to have higher grades in a related subject.
Requirements are likely to be higher for the most demanding courses. If you're thinking of taking four A-levels or the IB Diploma, for instance, you might be asked for six or seven GCSEs at grade 6 or better.
Your GCSEs are used as an indicator of how well you could do at A-level. Many sixth forms use them in a scoring system to predict how well you’re likely to do on their course.
For example, five grades at 5 or 6 and five grades of 4 or 5 at GCSE could be predicted as CCD at A-level, while straight 9-7 grades suggests you could get AAA.
If you're worried your grades might not cut it with the sixth form or college you want to go to, see if they're prepared to be flexible – otherwise, you may need to consider some alternatives such as resits.

2. GCSEs determine the qualifications you take next
Some sixth forms may say you can’t do a particular subject unless you’ve got at least a 6 or 7 in that subject at GCSE.
If your grades are mostly 4s or 5s, you might find opportunities to study A-levels are more limited. Instead, colleges might offer you a vocational course (which is more hands-on) such as a Btec Level 3 qualification instead.
That doesn't mean you can't go to university. Most universities accept applications with Btec qualifications.
3. GCSEs could be used to assess eligibility for a uni course
Regardless of the subject you want to study, the majority of university courses look for at least a grade 4 or 5 in English and maths.
Some university courses ask for specific subjects with certain grades at GCSE, so check directly with universities if you're in doubt.
But don't let your GCSEs put you off applying to the university course you really want – strong A-levels can outweigh weaker GCSE results, particularly if you expand on this in your personal statement.

4. GCSEs may limit the universities you can apply to
Some of the top academic universities (often belonging to the Russell Group) will ask for very high A-level grades – AAB or higher – for most courses.
Because of the assumed connection between your GCSE and A-level results, it'll be down to you to prove you’re able to achieve top grades. Grades 4 to 6 at GCSE suggest Cs and Ds at A-level – which might not be enough to get into some universities.
5. GCSEs can affect the career you end up doing
A career-related degree may also have subject-specific entry requirements:
- Engineering courses such as chemical engineering: you'll usually need A-levels or equivalent in chemistry and maths, and physics for other engineering courses, which in turn means you’ll need to have good GCSE grades in science and maths.
- Medicine: competitive courses like medicine may ask for top GCSEs across the board for English, maths and science subjects.
- Social work and secondary school teaching: grade 4 or 5 in GCSE English Language and maths.
- Nursing and primary school teaching: grade 4 or 5 in GCSE English, maths and science.
You can also put your grades on your CV when you're applying to part-time jobs at college or uni.
What you can do if your results don't go to plan?
Don't panic if you think one of your grades might hold you back – speak to teachers or a careers adviser about your options.
Resits
GCSE English and maths resits take place in November, so you could study for these alongside your A-levels. But you may need to wait until next summer if you need to resit more subjects.
Some universities might not accept GCSE retakes for competitive degrees like medicine; if you have an idea of what you want to study at university, research the entry requirements to see what's open to you.
Our GCSE forum is a great place to ask a question about retakes – or find out what other students are saying about them.
Remarks (review of marking)
If you get an unexpectedly low grade in your GCSEs, you can request a review of marking. This has to be done through your school or college, so you should discuss it with your teachers first. Find out more about requesting a review of marking on The Student Room.
The Student Room also has a comprehensive guide to all your post-GCSE options.
