How to Resit GCSE Biology

Didn't get the GCSE Biology grade you needed? It's frustrating when months of work don't pay off the way you'd hoped. Maybe you missed out on a place in sixth form, or perhaps you need a grade 4 to move forward with your plans. Either way, falling short in Biology can feel like a real setback.

Here's the good news: you can retake GCSE Biology. Thousands of students resit their GCSEs every year, and many go on to achieve much better results the second time around. With the right approach, a clearer revision plan, and lessons learned from your first attempt, you're in a strong position to improve.

This guide will walk you through everything you need to know about resitting GCSE Biology. As a biology teacher with over fifteen years experience I have supported countless students through the process of resitting their GCSE Biology exams. We'll cover when resits happen, how to register, what content you'll need to revise, and most importantly, how to prepare so you can boost your grade and get back on track.

Key Takeaways

• GCSE Biology resits typically take place in the summer exam period (May/June)

• You can resit as many times as you need until you achieve your target grade

• You don't need to redo your Required Practicals for a resit

• Your best grade always counts, so you can't lose marks by resitting

Who Should Consider Resitting GCSE Biology?

Resitting isn't for everyone, but it might be the right choice if any of these sound familiar:

• You didn't achieve a grade 4 (a standard pass) and need this for sixth form, college, or an apprenticeship

  • Many post-16 courses require at least a grade 4 in English, maths, and a science subject. According to (opens in a new tab)Ofqual (opens in a new tab), around 67% of students achieved a grade 4 or above in GCSE Biology in 2024, meaning a significant number need to resit

• You're aiming for a specific career or course that requires a higher Biology grade

  • Some A-Level Biology courses prefer a grade 6 or above at GCSE. If you're considering medicine, veterinary science, or related fields, a strong Biology foundation matters

• You know you underperformed and can do better

  • Perhaps exam nerves got the better of you, or you didn't revise effectively. A resit gives you a second chance to show what you're really capable of

When Can You Resit GCSE Biology?

GCSE Biology resits happen once a year during the summer exam period, typically in May and June.

You can't resit in November anymore. The exam boards stopped offering November resits for most GCSE subjects, including Biology. This means you'll need to wait until the following summer to retake your exam.

Both current students and private candidates can sit resits. If you're still in Year 11 or in sixth form, your school or college will usually enter you. If you've left school, you'll need to register as a private candidate through an exam centre.

There's no limit to how many times you can resit. You can keep attempting the exam until you achieve the grade you need.

How to Register for a GCSE Biology Resit

The registration process depends on whether you're still in education or sitting as a private candidate.

If you're still in school or college, speak to your exams officer or head of year. They'll handle your registration and let you know about deadlines. Your school will usually enter you at no extra cost if you're studying there, though some schools may charge a fee.

If you've left school, you'll need to find an exam centre that accepts private candidates. Not all schools and colleges do this, so you might need to search for dedicated private exam centres. You can find these by searching online for "GCSE exam centres near me" or "private GCSE exam centres UK."

Registration deadlines are typically in February or March for summer exams. Miss the deadline and you'll have to wait another year.

Costs for private candidates vary but expect to pay between £80 and £150 per exam, depending on the centre and exam board. Some centres charge additional administration fees, so check the total cost upfront.

What's Covered in a GCSE Biology Resit?

You'll be tested on exactly the same content as your first attempt. This includes all the topics from your exam board's specification.

The good news? You don't have to redo your Required Practicals. The practical skills you demonstrated during your course still count. 

Both Foundation and Higher tier papers are available. If you sat Foundation last time and want to aim higher, you can switch to Higher tier for your resit. However, make sure you're confident with the extra content and difficulty level before making this decision.

The exam format remains the same as your original exam board specifications. For AQA Biology: (opens in a new tab) two written papers, each worth 50% of your final grade. Questions will include multiple choice, short answer, and extended response questions.

How to Prepare for a GCSE Biology Resit

Preparing for a resit is different from revising the first time around. You've already sat the exam once, so you know what to expect. Use that knowledge to your advantage. As a biology teacher, here are my top tips that I advise you to consider.

Identify What Went Wrong Last Time

Before diving into revision, take an honest look at why things didn't work out last time.

Was it weak content knowledge? Maybe certain topics like genetics or photosynthesis never really clicked. If so, you'll need to spend extra time strengthening these areas. Our exam questions are organised topic by topic and allow you to track your progress through each one, meaning you can identify your strongest and weakest points.

Poor exam technique? Perhaps you ran out of time, misread questions, or didn't show enough working in calculation questions. These issues can be fixed with practice and better exam strategy.

Lack of revision? If you didn't put in enough hours or left it too late, you now know you need a more structured approach this time. At Save My Exams we have complete revision notes for all major GCSE Biology exam boards - you can work through topic by topic and tackle worked examples with helpful exam tips to guide you. 

Understanding what went wrong helps you target your revision more effectively.

Focus on High-Value Topics

Not all topics are equal in terms of exam marks. Some appear more frequently and carry more weight.

Check your exam board's specification and past papers to identify topics that come up regularly. For example, cell biology, enzymes, photosynthesis, and inheritance are consistently tested across all exam boards. We have put together a full collection of past papers and mark schemes to support your revision. 

Save My Exams' topic questions can help you identify which areas need the most work. Focus your revision on topics worth the most marks and those you struggled with previously.

Use Exam Board-Specific Resources

Every exam board (AQA, Edexcel, OCR, WJEC) has slightly different specifications and question styles. Make sure you're using resources matched to your exam board.

Download your exam board's specification below. This lists every topic you need to know and the depth of knowledge required.

• AQA GCSE Biology (opens in a new tab)

• Pearson Edexcel GCSE Biology (opens in a new tab)

• Cambridge OCR GCSE Biology A (opens in a new tab)

• WJEC GCSE Biology (opens in a new tab)

Study the mark schemes for past papers. These show you exactly what examiners are looking for in answers. 

Save My Exams revision notes are written specifically for each exam board, making them an excellent resource for targeted revision.

Practise with Past Papers

Past papers are your best friend when preparing for a resit. They help you get familiar with question styles, manage your time, and identify gaps in your knowledge.

Start with topic-by-topic questions to build confidence before attempting full papers. Save My Exams offers thousands of exam-style questions organised by specification point.

Once you're comfortable, move on to full past papers under timed conditions. This helps you build stamina and learn to pace yourself during the actual exam.

Always mark your work using the mark scheme and understand where you lost marks. Don't just tick or cross answers – work out why the examiner wanted a specific piece of information.

What Happens If You Get a Lower Grade?

Don't worry – you can't make things worse by resitting.

Your best grade always counts. If you achieve a lower grade in your resit than your original attempt, schools, colleges, and employers will see your higher grade. Universities and colleges generally accept the best grade achieved when considering applications.

Some universities prefer students who achieved their grades first time, but this mainly applies to A-Levels rather than GCSEs. For most courses, as long as you meet the entry requirements, it doesn't matter if you resit.

Your exam certificate will show all your attempts and the dates you sat each exam. However, when you apply for courses or jobs, you can choose to share only your best grade.

Frequently Asked Questions

Can I resit just GCSE Biology or do I have to retake all sciences?

You can resit individual science GCSEs without retaking the others. If you took Triple Science (separate Biology, Chemistry, and Physics GCSEs), you only need to resit Biology. If you took Combined Science and need to improve your overall grade, check with your school or exam centre about which papers to retake.

Is it harder to pass the GCSE Biology resit?

No, the difficulty level stays the same. Resit papers are no harder than the original papers. In fact, many students find resits easier because they're more familiar with the content and exam format. The pass boundaries might vary slightly each year, but this happens for all exams, not just resits.

Will I have to do the practicals again?

No, you don't need to redo your Required Practicals. Your practical endorsement from your original course still counts. You will, however, need to know the methods and be able to answer questions about these practicals in the written exam papers.

What happens if I fail the resit?

You can keep resitting until you achieve your target grade. There's no limit on the number of attempts. However, you'll need to wait until the next summer exam period and pay the registration fees again. If you fail multiple times, consider getting extra support through a tutor or alternative course before attempting again.

Final Thoughts

Resitting GCSE Biology isn't the end of the world – it's a fresh start.

Thousands of students improve their grades through resits every year. With a clearer understanding of what went wrong last time, a solid revision plan, and the right resources, you're in a much stronger position to succeed.

Remember, choosing to resit shows determination and maturity. You're taking responsibility for your future and refusing to settle for less than you're capable of. That's something to be proud of.

Start early, stay focused, and trust the process. You've got this.
