As long as you want to study for a month, it is no problem to recite the basics of high school mathematics.

Key points:

1. General Abstract Function+Exponential, Logarithmic, Power and Trigonometric Functions

2. Analytic geometry (straight line, circle, ellipse, hyperbola and parabola)

3. Solid geometry (proof+volume)

4. Vector (plane+solid)

5. Sequence+inequality+sine theorem+cosine theorem+permutation and combination probability sampling regression line+complex number

6. Derivative+Limit+Definite Integral

Five of them are miscellaneous subjects and six are preliminary calculus.

Everything else is important, especially trigonometric functions. It is difficult to analyze geometry with fractions, ie it is not difficult if you are talented.

As long as you want to learn, there is nothing you can't learn well. I suggest buying the Longmen series of books. These books are all good books and can be taught by yourself.

I hope you come on. It is not difficult to concentrate on the basics and brush the college entrance examination hard.

I'm not very good at science and physics.

Chemistry is nothing more than a few knowledge points that focus on compulsory courses.

There are fewer biological difficulties. Compulsory two is not too difficult to calculate. Only recite compulsory one and compulsory three.

The college entrance examination pays attention to Chinese. After strengthening, it is Chinese that can score.
