Combined with the competition outline, I systematically reviewed all the advanced mathematics knowledge I learned, mastered the basic methods in an all-round way and deeply understood the basic concepts. My goal is to reach an excellent level in the final exam, and I can answer half the questions in the initial exam.
The goal of this stage is relatively easy to achieve, and students with relatively weak skills can greatly improve their high mathematics level in this stage of review preparation competition. At this stage, refer to the textbook, JimiDovic, or CMC guide. If your goal is to participate in the preliminaries, then entering the first stage is not a problem.
Precautions:
If the goal of the competition is to "ensure the final", you need to further improve your problem-solving ability on the basis of the first stage. CMC proof (especially the proof of unary function) is a difficult problem, and it is difficult to think of many constructive proofs, which require a lot of practical and simulation exercises.
At this stage, it is suitable to use the "red test set" to practice your hands (that is, as long as you know how to solve or prove it, you will be able to write it without making mistakes). For some strong topic skills, even if you understand them once, you will forget them after a while, which requires repeated review until all the solutions to a topic are listed.
After the second stage of training, it has reached the final level of "no more than two major problems in the initial test can not be completely solved".
