How to resit your GCSEs

If your GCSE results weren't what you hoped for, a resit is a real option rather than a backup plan. Plenty of students retake one or two subjects and end up in a stronger position than they would have been the first time round.

This guide walks you through the four decisions you'll need to make: which subjects to resit, where to sit them, when to register, and what to do differently in your revision. It's written for students in England, but most of it applies across the UK.

Start by separating the subjects you have to resit from the ones you might want to resit.

In England, if you don't get a grade 4 in GCSE English language or maths, you have to keep studying that subject until you do. This is called the condition of funding rule, and it's set by the Department for Education (DfE). In plain terms: if you're in full-time education aged 16 to 19 (or up to 25 with an Education, Health and Care plan, often shortened to EHC plan), it applies to you, and you keep studying the subject until you pass or turn 19. Your sixth form, college, or training provider will usually enter you for the exam automatically. If your grade was a 2 or below, you can do Functional Skills Level 2 instead, which counts as an equivalent qualification under the same DfE rules.

For every other subject, a resit is your choice. Two questions are worth asking: does this grade matter for what you want to do next, and is the gap between the grade you got and the grade you need realistic to close in a few months? A jump from a grade 3 to a grade 4 in one subject is very different from trying to push a grade 6 up to a grade 9 across three subjects at once. In most cases, resitting one or two priority subjects works better than spreading yourself thin across four or five.

Some students resit even when they've already passed. If you got a grade 5 and want to push for a 6 or 7 because it matters for a sixth form, college, or university course, that's a perfectly valid reason. The process is the same as for any other resit, you just usually pay yourself rather than the school covering it.

You've got four realistic options for where to sit your exam, and the right one depends on your age, what you're resitting, and how much support you want. English language and maths resits are typically free if your school or college enters you. Other subjects almost always involve paying a private exam centre (a school or organisation that runs exams for outside candidates).

There are two resit windows each year, and the Joint Council for Qualifications (JCQ, the body that publishes the official exam calendar) sets the dates.

The November series runs in early November and only covers GCSE English language and maths. Results come out in mid-January, with November 2026 results landing on Thursday 14 January 2027. The June series is the main exam window and covers every GCSE subject, with results in late August on the same day as year 11.

Deadlines matter, and they're earlier than most students expect. For the November series, exam centres usually close entries in early October (AQA's recent deadline was 4 October), and some private centres set their own internal cut-off a week or two before that. For the June series, the standard entry deadline is 21 February. Late entries are accepted until around mid-March, but they cost more.

If your old school or college is entering you, ask them in writing well before the deadline to confirm you're on their entry list. If you're going private, contact the exam centre directly and check whether they need anything from you beyond the entry form, like proof of ID or a previous results slip.

The biggest mistake students make with resits is doing the same revision again, just harder. If re-reading your notes and watching videos didn't get you the grade last time, doing more of it won't get you there this time either.

Start with your previous exam papers if you can get hold of them. Most schools will release them on request. Look at where you lost marks and group the errors: were they topics you never really learned, mark scheme misreadings, time pressure, or careless mistakes? Each one needs a different fix.

Then build your revision around past papers and active recall instead of passive reading. You've already covered the content once, so the gap between where you are and where you need to be is usually about exam technique more than new material. Doing one full past paper under timed conditions and marking it honestly tells you more than ten hours of re-reading.

If you're 16 to 19 in full-time education resitting English language or maths, the cost is zero. Your school or college handles the entry and the fee under the DfE condition of funding rules (which apply until you pass or turn 19).

If you're resitting any other subject, or if you've left education, you'll typically go through a private exam centre. Looking at the current private candidate pages from AQA, Edexcel, and OCR (the three main exam boards), standard entry fees usually land between £270 and £425 per subject once the centre's admin charge is added on top of the board's base fee. Science subjects with practical endorsements can cost more, often £400 plus. Pearson Edexcel also notes that late entries can add a 50 to 100 percent surcharge, so registering on time is the single easiest way to save money.

Some adult education colleges offer subsidised or free GCSE English and maths courses with the exam included if you're over 19. It's worth checking what's available locally before going private.
