Mathematics: 4- 1 is plane geometry. It is recommended that students with good basic knowledge in junior high school choose it, which is relatively simple for such people; 4-4 There are not many things that need to be leveled, mainly the accuracy of calculation. It is suggested that students who calculate more carefully choose; 4-5 inequality should look at what kind of problems? If it is to solve absolute inequality, it is particularly simple. If it is to prove inequality, it is difficult and takes a long time. Therefore, you can't put all your eggs in one basket. Personal advice is to learn 4-4 well, and the problem is not difficult to calculate. If 4-5 is to solve the absolute inequality in the exam, you must choose and not learn.

Chemistry: it is much easier to choose 3 than 5, and it is easy to score in the exam.

Biology: Choosing 1 is much more than memorizing 3. Choosing 1 is relatively simple, but the history of choosing 1 is short and the routine is still unclear. Choosing 3 takes too long, the questions are complex and diverse, and the difficulty is getting bigger and bigger. Last year's election 3 was simply a big pit!
