Find out how to handle results day, whatever your grades...
Beyond that, it's just a matter of preparing yourself mentally. Remember: your exam results won't determine the rest of your life, and there is plenty that you can do if you don't get the grades you hoped for. If you are nervous, try to talk to somebody who has been in your position before - they can help you to keep the situation in perspective. Finally, arrange something fun to do after you collect your results.
You might be able to get your results online. This will depend on your school and your exam board, so ask about this in advance.
Remember that you don't have to open your results with your friends, parents, teachers or anyone else. If you're worried or nervous, you can take them somewhere to open them on your own - but remember that having people who care about you nearby can be a good thing whatever your results.
Some universities and university courses do have extra GCSE requirements. For example, a university might only take people with a C or above in English and maths, and might require a certain number of Bs or above for competitive courses like medicine.
However, other universities don't have GCSE requirements at all, so your GCSE grades won't mean that you won't be able to go to university. Additionally, you will normally be able to retake GCSEs alongside your A-levels.
If you want to get an exam re-marked, talk to your subject teacher about it. There may be a fee, although sometimes the school will pay for this, and either way the money will be returned if your mark goes up enough to change your overall grade.
Make sure you make the most of the time before you resit the exam. You may be able to take extra lessons at your school or college, especially if you are retaking GCSEs alongside doing A-levels. If not, some colleges offer special courses for people who want to retake GCSEs.
It's no longer possible to retake individual modules of your GCSEs. You'll need to do all your exams again.
You will normally have to pay to retake a GCSE. The amount can vary depending on where you do the exam, so talk to your school about the cost.
