Active thinking: Many students just listen and can't take the initiative to think, so when they encounter practical problems, they don't know how to apply what they have learned to answer them. The main reason is that you didn't consider the trouble caused in class. In addition to following the teacher's thinking, we should also think more about why we define it like this, and what are the benefits of solving problems like this. Through active thinking, we can not only listen more carefully, but also stimulate our interest in some knowledge and help us learn more.

Precautions:
Go through the questions from beginning to end, so that you know what you are doing and answer them from the beginning.
Seize 5 minutes before the exam, read the multiple-choice questions, by the way, tick the correct answers to the first few questions that must be scored, and check them again during the formal exam, so that you will quickly enter the answering state (because you are nervous at first, it is very important to answer the first few questions well), so that the multiple-choice questions have been completed, and check them again, which not only makes full use of the time, but also adjusts to enter the exam state, which is the best of both worlds.
