Mathematics in senior three is really not easy, but you can pass it, which shows that you have the ability to conquer this subject, but mathematics in senior two will be a little more difficult. If you think it's too difficult, I can give you some advice.
First, you need to mark the wrong questions after each exam, and then try to solve them immediately. Don't use the wrong book, because high school time is tight and a little wasteful. You just need to mark the wrong questions in a more conspicuous color and sort them out.
Secondly, if you have spare capacity, you can write some college entrance examination questions. Ge Kun's Zhenti 2000 is recommended here, because this book covers all areas of the college entrance examination, and makes the test sites of the college entrance examination clear one by one, which is convenient for marking.
Thirdly, if you are a new college entrance examination, please add a little more, that is, read more formulas and theorems in textbooks. You should learn to make them your magic weapon and train your mind regularly.
Fourth, problems must be solved. You can consult your teachers and classmates, but it is best to think for help yourself.
Hope to adopt, thank you.
