The big topics are: sequence, trigonometric function, solid geometry, probability statistics.

These four types of questions are relatively simple compared with conic and derivative questions, but we still need time more or less. It is very necessary to sort out and summarize the necessary question templates:

The most typical example is scientific solid geometry. When you look at the test paper, 90% of the second question is to find the dihedral angle. If you do it in the conventional way, the probability of making mistakes will be very high and it will be a waste of time. So when you look at the reference answers, you will find that the answers are basically space vector method. This is actually a hint, you can do it with vector method, but actually mastering the template of vector method can help you shorten a lot of time.
