First of all, there is still about half a year before the college entrance examination.

You can find a reliable teacher and analyze your local college entrance examination math paper to see which questions are required.

I'll just give you a few examples, such as:

Solving the first question will definitely take the trigonometric function class. You can recite the formula, let the teacher teach you how to solve the problem, and then do it yourself to see if you can get the correct answer. If not, keep asking the teacher. If the teacher's comment on writing is that you must get full marks for this kind of question, then you should practice more to ensure that you do well.

Answer the second question, the derivative formula must be memorized, ask the teacher+do the problem as above. If the teacher says that the second big question must get full marks, then you should do more questions and consolidate your knowledge.

Answer the third question of conic section. If the teacher says that the third question of this kind of problem is difficult and you can give up, then you should focus on the first two questions. Practice more and recite the formula.

Answer the fourth question, test the series and recite the formula. If the teacher says you can give up the third question, you should focus on the basic questions of the first and second questions. Remember to practice more and ask the teacher more.

For example, the first question of multiple-choice questions is generally tested in the collection, so take a good look at the basis of the collection. That set is very simple, you must learn it.

I know this process must be difficult and painful.

Learning is a painful process, so is any new knowledge, not just mathematics.

But it's really too early to give up now. I will never give up until the last moment.

I hope you, as the protagonist of your life, don't give up.
