The frequently asked and required sections in the elective course 1- 1 are the application of logical terms, conic curves and derivatives, among which the application of conic curves and derivatives is more difficult.

The frequent and required chapters of elective course 1-2 are algebraic operation, block diagram, reasoning proof and statistical cases of complex numbers, in which the algebraic operation of complex numbers is relatively simple, the algorithm of reading block diagram is not complicated, and the reasoning proof of the first question of solid geometry is generally simple. As long as statistical cases can memorize formulas and understand principles, it is not difficult to remind people that there are many words.
