It is very important to recite in advance in summer vacation. The mentality of taking the exam after reciting the book is very confident, otherwise you will panic. Recite during the summer vacation and read at least four books. Actually, I think it's too hard to recite four books in two months ... but you have perseverance! Encourage you! )
It doesn't make sense to do problems when you are not familiar with books, but don't forget to do more political problems after school starts. Our teacher said that the time for reciting and doing problems should be equal.
Just buy that thick math "book" with concepts, good topics and, more importantly, detailed independent answers. I finished 20 sets of "comprehensive papers" before the third year of high school, which was very effective.
Summer vacation to sort out the concept of mathematics, oh, some people say that liberal arts students, those who get mathematics get the world ~
You can ask me again if you have any questions ~
