3. 6 Ways to Check for Mistakes in A-Level Maths
How could I ensure that my answer is right in the A-Level Maths exam? Or Which ways can I use to check my answer? There is no best way to absolutely ensure your answers are always right. However, some ways are useful for you to check your answer at least in the right place.
3.1 Review your answer
When you are not sure of your answer, you should ask the question, Does it answer the question properly? and try to prove it yes or no.
- Replace your answer as x, y, or anything you want to check whether your equation is operating or not. You can apply this way for equation question form.
- Take a random line in the midst of proof and check that if you substitute in random variables, the left-hand side and right-hand side give you the same value or not.
- Check to see if the shape you have already created “works” in another way if you have worked with geometric questions.
3.2 Make sure your response is reasonable
When you get a response, especially a measurement, it’s a good idea to ask yourself, “Is this a realistic response?”. For example, Lan rides a bike in 10 minutes then you calculate the length of distance as 10km. Surely, the answer is impossible.
3.3 Review the list “Stupid List”
When you practice mock exams or exercises, you should write and highlight your mistakes after checking the results. Then you make a list to resume all of your mistakes called a “stupid list”.

3.4 Examine each and every line
Do you have some spare time? You might either count the tiles on the ceiling or check your work line by line. It is recommended that you place a ruler under the first line that you have written your answer.

Verify that what you’ve written corresponds to the line above it. Continue to the following line until you are satisfied. Then move on to the next lines. Even if the process is really tedious, it helps you a lot.
3.5 Re-read the question
You have spent many times solving a question; however, you feel that you go nowhere next. At this moment, you get stuck. So, what should I do? To smooth your process, you can do as below:
- Check to see if you’ve used any of the information provided by the examiners. Is it of any use to you?
- Check that the information you have used is valid and that any formulas you will need have been copied correctly. (it is much easier to notice whether you have written them down incorrectly in case you know them by heart.)
- Check to see if there’s anything you can use from earlier in the problem. There are numerous exam questions relating to previous parts.
3.6 Search for a different strategy to solve the questions
Any question can be answered in a variety of ways. If you have been trapped, lost, or traveled in the wrong direction, it might be worth your time searching for one of these. Try performing anything without the calculator if you’ve done it before. Try a different equation for a straight line if you have already used one. If you have already tested the quotient rule, try it with the chain and product rules.
