1, and improve the one-time accuracy rate. That is to say, when doing problems, under the condition of properly controlling time, slow down the speed of doing problems, think clearly about every problem, and write down every step to ensure correctness. Relatively speaking, it will be slower, but the correct rate will be higher.

2, improve the speed of doing the problem, and leave enough inspection time. Some careless topics are often done too quickly and ignored. So, if you do the problem quickly by yourself, you might as well leave yourself a little sufficient time for investigation. After all, check again from the topic with the highest score. You can even do a question in different ways to verify your answer. In this way, carelessness can also be reduced through inspection.

The above two methods vary from person to person and can be used selectively. I hope they can help you.
