The most important thing is to sort out the knowledge system of the subject. When you see a topic, you clearly know which theoretical knowledge in the system, which column and which formula to use-to "understand".
Then we should summarize the classic questions. After studying each question, we should practice three or five similar exercises to consolidate the absorbed knowledge-to ensure that we can do it.
At the end of the stage study, you should do a certain number of comprehensive exercise papers, speed up the pace, and try your best to improve the correct rate-to ensure that you can "score" in the exam.
Knowing, doing and dividing-learning science is almost the same thing.
