Everything can be tested. But most of the tests are linear functions and equations, inequalities (there may be two fill-in-the-blank or choices here, and most of them will be application questions); The degree of data fluctuation (generally drawing and filling in forms, 8 points for each question); Quadratic roots of Pythagorean Theorem (generally formula problems, which often appear in filling in the blanks or choosing) (8 points for calculation problems, and occasionally 10 points for application problems).

If it's not good, I hope someone can give me some advice.
