The number three is particularly simple, and the main test is probability, which is nothing more than a few questions. As long as you do these questions more, you will naturally know how to do them.

Of course, first of all, you have to read books, look at the textbooks used in previous classes and look back. At this time, you need to study again, solve one problem at a time, and don't give up because you don't understand. But it's very important for you to find an exam outline to review, because the outline content of 123 is different and what you need to learn is different. Look at the textbook and do it in combination with after-class exercises. After reading the textbook, I feel almost done. I can do some topics and read review books at the same time. There is a review book specifically for the number three.

It doesn't matter even if it's based on 0. One year is enough time to study and review. Come on! Ask again if you don't understand ~ ~
