First, you have to know all the contents of each module. Be able to read and think about the topic initially. On the other hand, if you encounter a simple topic or a familiar topic, you can get a score.
The second is to attack each module step by step and arrange what you are good at or not good at in a certain order.
Then it is difficult to break through and do a lot of exercises. Learning in the second test is no better than trying. You should learn to think about a problem for a long time, learn to constantly challenge it, and try to solve it with your own ideas instead of simply learning the existing answers.
Finally, simulation training before the exam. Looking for the feeling of the league. At the same time, in the process of doing the problem, find the unfamiliar plate to check for leaks and fill vacancies, and strive to get higher scores in the league.
