Mathematics: Compulsory 4&; 5 is the key point, trigonometric function must be thoroughly studied;

The content of elective course 2- 1 will produce a moderately difficult;

It is difficult to choose the content of 2-3 permutation and combination, but the general topic is very simple;

For students with weak spatial imagination, there is compulsory 2.

But don't lose heart, listen as much as possible, and it will be much easier to master the use of vectors later.

Do 2-2 derivatives, recite formulas, and do more questions, and you can easily get sub-questions.

Physics elective content is coherent, as long as it is not chaotic. Personally, electricity is better than mechanics.

There is a lot of knowledge about the extension of chemical reaction principle, so you should always remember it.

Biology is the best subject to learn, but it is not easy to test. Personally, students who live on biology, please don't put too many chips on this topic.

Compulsory 2 Genetics is best previewed before class.

Learn compulsory 2 well, you can be confident in learning biology, but don't be proud. It is also difficult to choose 3.
