Look back at a recent answer and find the first step that went wrong. Did you choose the wrong method, make an arithmetic error or run out of time? Use that answer to choose what to practise.

Find out which problem you actually have

Sit a timed set of past questions on a topic and mark it carefully against the actual marking scheme, not just the final answer. Then sort your mistakes into three categories:

  • Conceptual gaps — you didn't know the method, or used the wrong one entirely.
  • Careless errors — you knew the method, but made an arithmetic slip, misread the question, or dropped a sign.
  • Time pressure — you knew what to do but didn't finish, or rushed the last few questions.

Check which kinds of error recur in your own work. An explanation may help with a missing concept; a written checking routine may help with a sign or unit error.

If it's a conceptual gap: rebuild it from a worked example, then do it yourself

Read a worked example that explains each step. Close it and attempt a similar question. If you get stuck, review that step and try again. This applies active recall to Mathematics while keeping the focus on the method.

If it's careless errors: slow down the checking, not the working

Careless errors usually come from one habit: moving to the next line before confirming the current one is right. A few concrete fixes that actually change this:

  • Write every step, even ones you could do in your head — it gives you something to check and makes it easier to find where an error crept in.
  • After finishing a question, estimate roughly what the answer should look like and check your actual answer against that estimate. A probability answer greater than 1, or a triangle's angles not summing to 180°, should jump out immediately.
  • Double-check the specific things you personally get wrong most often — for most students it's sign errors, misreading a decimal, or copying a number wrong from one line to the next. You'll know your own pattern once you start tracking mistakes instead of just moving past them.

If it's time pressure: practice under the actual exam timing, not untimed

Once you can use a method, try a small timed set. Note where you slow down, then practise that question type separately. Use your school's current paper guidance when choosing time limits.

Method marks matter even when your final answer is wrong

Show each step and include units where required. Compare your working with the relevant mark scheme or ask your teacher which parts need more explanation.

Don't let one bad topic stall the rest of your revision

If a topic remains confusing after a focused session, record the exact step you need help with. Ask a teacher or return to a worked example, while keeping time for the other topics on your syllabus.

Frequently asked

Why do I keep losing marks in Maths even though I understand the topic?

Usually one of three things: arithmetic slips under time pressure, skipping working (which loses method marks even with a correct final answer), or running out of time on later questions because earlier ones took too long. Timed past-question practice, marked against the actual marking scheme, is the fastest way to find out which one is happening to you.
