How important are your GCSE grades?

You have your GCSE results - congratulations! Now it's time to see how those GCSE grades will shape your next few steps, post-Year 11.

Update for 2017 GCSE results: we've also taken a closer look at whether this year's English and maths grade and curriculum changes could make a difference to your future plans. Read on for more...

In a nutshell, your GCSE results could affect the following:

For ease, we're referring to the A*-G GCSE grading system below, alongside the new 9-1 grades. Read about GCSE grade changes here, which affect this year's English and maths results.

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 4-5 in the new 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.

This year, with a new curriculum and grading system in place for English and maths to contend with, there may be additional leeway as the changes settle in.

2. GCSEs determine the qualifications you take next

Some sixth forms may say you can’t do a particular subject unless you’ve get 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.

3. They 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 new strucuture.

Some university courses go further and ask for specific subjects at GCSE, with certain grades, so check direct with a university if you're in doubt. For example:

  • Management at the University of Leeds specifies that you must have at least a grade B (roughly a 5 or 6) in English language and maths under your belt.
  • Psychology at the University of Bath asks for 'a strong set of GCSEs, such as grade A*, 8 or 9 in at least five relevant GCSEs or grade A or 7 in the majority of GCSEs. We strongly prefer applicants who can demonstrate a solid grounding in mathematics or statistics, such as those with GCSE grade A or 7 in mathematics.'
  • Law at Manchester Metropolitan University will accept applicants with GCSE grade C or 4 in English language or Level 2 Functional Skills English.

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 with A-level reforms also underway, universities might use your GCSE grades more than before when deciding whether to accept you or not.

    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.

    Here's another example. Applicants to LSE need to have 'achieved a strong set of GCSE grades including the majority at A and A*, or equivalent. Your GCSE (or equivalent) English language and mathematics grades should be no lower than B. We also consider your overall GCSE subject profile, and your AS grades, if available.'

    5. They could 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 about the new 9-1 grades in English and maths?

    If you're picking up exam results on Thursday 24 August, your grades for English literature, English language and maths will look a little different to the rest of your results, with numerical 9-1 grades awarded rather than alphabetical A*-G grades in those subjects.

    Here's how the new 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 that your results will include a mixture of old and new-style grades.

    Worried about your results?

    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 enquiries directly with their examining board, so it will be up to them to decide if you've got a strong case or not.
