How important are your GCSE grades?

Find out how GCSEs affect your future choices and studies, and what to do if they don't go to plan.

Your GCSE results are a very important part of your academic journey. The results you get can affect the following:


What are GCSEs?

GCSEs (General Certificate of Secondary Education) are subject-based academic qualifications. Students study towards GCSEs at secondary school in England and Wales over a period of two years, usually in Year 10 and 11.

GCSEs have changed in recent years, including how they're graded.


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 – ranging from four to five C grades (that's between a 4 and 5 under the changed GCSE grading system), with perhaps Bs in the subjects you want to study, through to at least six GCSEs at grade A for the most selective colleges.

Your GCSE performance is usually a good indicator of how well you’ll do in A-level or other advanced studies – in fact, it’s the only real hard-and-fast evidence of your academic abilities a college has to go on. Many sixth forms use a scoring system, based on GCSE grades, to predict how well you’re likely to do (and from that, decide whether or not to accept you).

For instance, five B grades (roughly 5 or 6) and five C grades (roughly 4 or 5) at GCSE could roughly translate to a predicted CCD at A-level, while straight A grades would suggest AAA is possible.

The lower your GCSE grades, the lower you’ll be scored – which could limit the number of colleges and sixth forms open to you.

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 approach some alternatives. Learn more about what to do if your grades don't go to plan.

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 grade A (at least a 6 or 7) in that subject at GCSE.

If your grades are mostly Cs (4 or 5), studying A-levels or Advanced Highers could be off limits altogether; a sixth form may offer you a vocational (ie a more practical and hands-on) course such as a BTEC Level 3 qualification instead. Most universities accept Btec qualifications, by the way.

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 C grade in English, maths and perhaps science – that's grade 4 or 5 under the revised structure.

Some university courses go further and ask for specific subjects at GCSE, with certain grades, so check directly with universities if you're in doubt.

Don't let a disappointing GCSE performance put you off applying to the university course you really want, though – a good AS-level performance, for instance, could outweigh a set of weaker GCSE results, particularly if you expand on this in your personal statement.

But given recent A-level reforms, universities might use your GCSE grades more than before when deciding whether to accept you or not.

Search for a course now to see full entry requirements and everything else you need to know.

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 B and C (or a 4 to 6) at GCSE are suggestive of Cs and Ds at A-level – which won't be enough to get into some universities.
The more competitive the university and course, the higher the number of high-achieving students with top GCSE marks applying. Some courses actively state this, like the University of Bath example above.


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 a whole suite of good GCSEs. The University of Birmingham’s medical school, for example, specifies ‘normally, applicants must offer A* grades in each of English (either English Language or English Literature), mathematics and all science subjects. Integrated Science (double certificate) is acceptable as an alternative to single sciences. Overall GCSE performance will be considered.’
  • Social work and secondary school teaching: these professions won’t consider you without at least a grade C (or 4 or 5) in maths and English language at GCSE.
  • Nursing and primary school teaching: grade C (or 4 or 5) in GCSE English, maths and science. 

And when it comes to employment right now – for that weekend job while you're doing your A-levels or a part-time job at uni – your academic grades will go on your CV, too.

What do the 9-1 grades mean?

Since September 2017, the way GCSEs are graded has changed, moving from the alphabetical system of A*-G grades to the numerical 9-1 system.

In the numerical grading system:
  • 9 is higher than a current A*
  • 8 is between an A* and A.
  • 7 is equal to an A
  • 6 is equivalent to a high B  
  • 5 is between a B and C
  • 4 is equal to a grade C
  • 3 is in between a D and E
  • 2 is between an E and F
  • 1 is a G
  • U refers to an ungraded paper
See the diagram below to see how the revised grade system stacks up:

As you can see in the table above, old and new grades don't match up like-for-like. However, a 4 is being classified as a standard pass, which can be broadly compared to a grade C, while a 5 is a strong pass.

Grades 9-7 are roughly equivalent to the old top grades of A* and A.

If you're unclear what your grades mean or how they compare, speak to a teacher or check out guidance to GCSE entry requirements offered by individual universities. Sixth forms, colleges, and universities will be well aware of the changes to the curriculum and the new-style grades.


What you can do if your results don't go to plan?

If you're concerned that one or more of your results might hold you back, don't panic – speak to teachers or a careers adviser about your options.


English literature, language and maths GCSE resits take place in November. If you're willing to work hard it could be feasible to study for these (perhaps in the evening, perhaps through a different college) alongside the rest of your timetable. If you need to resit more subjects, you may need to wait until next summer.

Bear in mind that for very competitive degree courses such as medicine, universities might not accept GCSE retakes; so if you have an idea of what you want to study at university, spend time researching the entry requirements of a range of courses to see what's open to you.


If you're not happy with an exam result and you think it may be incorrect, it's important to first talk to your school or college. Students can’t make inquiries directly with their examining board, so it will be up to them to decide if you've got a strong case or not.
