*During maths tests, choose 'prove that' type problems as much as possible. Because there is no need of re-checking these problems, and you can be sure that you've written the correct answer.

*Most of the maths problems have more than one solving methods. While re-checking such problems, always check using alternative methods, not using the same method you used. Check whether both the answers are same. This way, you can detect careless mistakes.
