What to choose: Submitting materials is similar to "resume", that is, something that can prove one's ability level. As for the written test and interview, for the school computer, the written test is some arithmetic problems, while for the school mathematics, the written test is mainly a few points. School computer interview is basically a form of mobile terminal development in big factories.
The school has at least one cycle, and the last one is eliminated (returning to the corresponding basic class after elimination). It is difficult to take the school examination, and the academic system 100% is exempt from the examination. (As far as I know, 16 is the last one in the physics direction of the school. )
Ps: Taishan College is equivalent to a virtual college, which is divided into five directions: mathematics, physics, chemistry and biological computer. The five majors are managed by the corresponding colleges. You don't need to go in and lie flat. The exemption requirements are, for example, CET-6 needs to pass the xx line, and the GPA cannot be lower than 80, and so on.
