In math class, my mental arithmetic is faster than others' pen arithmetic, and the correct rate is also high, but I always feel that I have made a mistake in the exam. What should we do?
During the exam, you just need to write down what you know. As long as you are quick and accurate in mental arithmetic, don't doubt yourself during the exam. If you are capable, you can do well in the exam at any time. Just answer the questions boldly according to your mental arithmetic results. Always doubting yourself will only make you more nervous and unable to show your level. Believe in yourself: I am an expert, and I will do well in the exam!
