10 Maths Exam Tips That Actually Work
Maths exams are not just about knowing the content. How you approach the exam matters just as much. These ten tips have been proven to improve grades, whether you are sitting GCSEs, A-Levels or university exams.
1. Always Show Your Working
Even if you can do a calculation in your head, write out every step. Examiners award method marks, so even if your final answer is wrong, you can still pick up most of the marks. For a 5-mark question, the final answer is usually only worth 1 mark. The other 4 marks are for method.
2. Read the Question Twice
The most common reason students lose marks is not answering what was actually asked. Read the question once to understand it, then again to catch key words like "hence", "show that", "exact value" or "give your answer to 3 significant figures". These words tell you exactly what form the answer should be in.
3. Check Your Units
If the question gives measurements in centimetres but asks for the answer in metres, you must convert. Unit errors are one of the easiest marks to lose and one of the easiest to avoid. Circle the units in the question so you do not forget.
4. Draw Diagrams
For geometry, trigonometry and graph questions, a clear diagram can make the solution obvious. Label everything. Even for questions that do not explicitly ask for a diagram, drawing one helps you visualise the problem and reduces errors.
5. Manage Your Time
As a rule of thumb, you should spend roughly one minute per mark. A 4-mark question should take about 4 minutes. If you are stuck after double that time, move on and come back later. It is better to attempt every question than to perfect one and miss three.
6. Start With What You Know
You do not have to answer questions in order. Scan through the paper first and start with questions you are confident about. This builds momentum, calms nerves, and ensures you bank easy marks before tackling harder ones.
7. Use Estimation to Check Answers
After calculating an answer, do a quick sanity check. If you are calculating the area of a room and get 0.3 square metres, something has gone wrong. Round numbers to easy values and estimate what the answer should be roughly. This catches major errors.
8. Know Your Calculator
Practice with the exact calculator you will use in the exam. Know how to use the fraction button, the memory function, and how to switch between degrees and radians. Do not waste exam time figuring out buttons. Make sure it has fresh batteries.
9. Do Not Leave Blanks
Even if you have no idea, write something. Write down a relevant formula, substitute in the values from the question, draw a diagram. You might earn 1 or 2 marks from a 5-mark question just by showing you know where to start. Those marks add up across a whole paper.
10. Review With Fresh Eyes
If you finish early, do not just sit there. Go back through your answers and check them as if someone else wrote them. Re-read each question and make sure your answer actually addresses it. Check arithmetic by working backwards. Many students gain 5-10 extra marks just from a careful review.
