GCSE Chemistry is split into two different papers, each of which focus on different parts of the course. Both are equally important, and you'll need to be confident with the whole list of topics mentioned if you want to land the best marks possible.
| Paper | What you'll cover | How Long Is It? | What to Expect |
|---|---|---|---|
| Paper 1 | Energy chances, atomic structure, bonding, chemical changes | 1 hr 45 mins | A mix of multiple choice and short and long form questions |
| Paper 2 | Rates of reaction, organic chemistry, chemical anaysis, the atmosphere | 1 hr 45 mins | Same format as above |

Use of the Exam Mark Scheme
Mark schemes are a great way to work out where you’ve gained and lost marks, and how well you’re answering the questions. Even if you know a topic well, you can easily drop marks by not phrasing your answers the way examiners expect. Find a physics and chemistry tutor now.
In order to mark effectively, you'll need to:
- Identify key terms: Some marks depend on using specific vocabulary or hitting exact points
- Self mark your work: Try to examine your work like the examiner would, checking if you've answered the questions correctly
- Focus your revision: Make sure you take notice of patterns where you consistently lose marks and focus on those areas during study
- Write model answers: Practice writing full answers that clearly follow the mark scheme, using correct terms and logical explanations
- Peer marking: Swap papers with friends to get honest feedback and to spot missing points you might not have noticed
Before you start writing, it's a good idea to highlight any key action words in the question (explain, describe, evaluate, etc). This will help you stay focused and keep you from accidentally answering the wrong type of question.
Learn the Structure of the Exam Paper
Understanding the exact structure of the exam paper is really important if you want to mange your time effectively and maximise your changes of getting good marks. But what do you need to watch out for? Let's take a look at this below:
Is the paper divided into multiple sections like multiple choice, short answers, or extended writing?
If a section carries more marks, it usually deserves more time spent on it. Try to train yourself to timing during practice papers to avoid rushing the final questions.
Check that you have revised every topic listed in the specific thoroughly. Missing one section could mean missing 10% of the paper or more!
Try to practice answering multiple choice questions quickly while spending more time crafting longer detailed answers for written sections.
You can check out the examiner's report every year? This report details the common mistakes students have made during their exams. By reading it, you can learn what not to do, and what common mistakes you need to avoid.
Take a Look at the Exam Board Specification
At times, knowing what's actually going to pop up on the exam is half the battle. Thankfully, your exam board's specification can give you a great idea of topics and types of questions likely to appear, helping taking some of the guesswork away as a result. Check here for an online Chemistry tutor now. Here's how to make the most of it:
Always ensure you're using the latest (2025) specification for your exam board. There's always the chance that older versions won't match the current assessment style
As you practice, match every note and textbook section to the points listed. Having a tough time easily explaining a point? Make sure you flag it for extra study later
Past papers often repeat core topics like bonding, rates of reaction, and energy changes. Use the specification to track which areas are tested the most
Want to stay motivated? Make sure you make a list of each topic once you've properly learned it. Not only will it massively boost your confidence but also show you what's left to learn
Ask For Help From Your Friends
Revising as a group is really useful for getting a complete picture. It can sometimes be overwhelming when you’re going through your own work.
| Plan and swap | Peer Mark Carefully | Build Model Answers |
|---|---|---|
| Answer a few last paper questions first, then swap with your friends to see if there's much difference in how you've answered them | Mark each other's work using the proper mark schemes. Watch out for things like unfinished explanations and areas where you almost got full marks but need a bit of work | Work alongside your peers to write out full and detailed answers for harder questions. Make sure your model covers all the points an examiner would expect to see for top marks |
If you can explain a particularly tricky topic to a friend, you're probably ready to answer any sort of similar question that pops up in your exam!
Time yourself
Make sure you do some of your past papers in exam-like conditions. While discussing the papers with friends is a useful tool, practising a paper under restricted time and without any revision notes is also really important.
✏️Set Up Your Space
Find somewhere nice and quiet where you won't be disturbed. Turn off your phone, clear your desk, and make sure you have everything ready to begin
⏰Stick to Strict Timing
Set a countdown for the full paper (1 hour 45 minutes for Chemistry). Try and stick to this time without pausing or giving yourself extra time
✅ Mark it Soon After
Go through your answers quickly once you're completely finished. Use the official mark scheme to find out where you dropped marks
Where to Find Past Papers
You can find past papers and chief examiner reports on the website of your exam board.
There you’ll find past papers from previous years and there will also usually be papers from summer exams and resit periods so there will be plenty to practice with.
| Exam Board | Links to Past Papers |
|---|---|
| Exdecel (Pearson) | Edexcel GCSE Chemistry Past Papers |
| AQA | AQA GCSE Chemistry Assessment Resources |
| OCR | OCR Gateway Chemistry A (J248) Past Papers |
| Eduqas/ WJEC | WJEC/Eduqas Chemistry Past Papers |
Your teachers at school will most likely give you past papers to practice in class and will read through the question structures with you so you’re best prepared.
Other resources like student room and BBC bitesize are also great tools for finding past papers and other tips.
Private Tutoring
If you need some more structure in your revision and want someone to hold you accountable it can be helpful to get a private tutor. Below we outline some of the most common ways a private tutor can help you with exam prep.
Tutors are experts and finding patterns in their students mistakes and can show you how to avoid dropping easy points from the get go
Confused by tricky areas of chemistry like bonding and chemical reactions? Tutors can break down these topics bit by bit and explain them in a simple way you're guaranteed to remember
A tutor will make sure you're revising enough, and provide encouragement and motivation when you're feeling anxious or discouraged
They can also help you build a proper revision plan, avoid wasting time, and help you focus on the topics that need the most attention
