Look at your own advantages and disadvantages. The application of the setting function is mandatory. These three contents are all about it.

Compulsory two solid geometry and analytic geometry.

Compulsory three probability statistics and algorithms, this is the simplest.

Compulsory four trigonometric function plane vector

The inequality of triangle (sine theorem and cosine theorem) sequence must be solved in five ways.

Optional 2- 1 cone space vector

Take 2-2 backward method to prove number system and complex number.

Selective 2-3 permutation combination random variable

The remaining elective course 4 begins with lectures, including geometric proof matrix and transformation inequality lectures, etc.

If you don't learn every knowledge point clearly and thoroughly.

Then finally, the questioner will synthesize many knowledge points, which is the most difficult!

Therefore, we should learn every knowledge well and thoroughly.

Come on!
