Mathematical logic is strong, which is related to primary school, junior high school and senior high school.

My suggestion is:

1, find all the textbooks you have studied. First look at the basic knowledge and understand the basic definition. The second is to do all the examples (don't look at the answers, compare the answers after you finish).

2. There is a saying in China that "learning the sea is endless". After studying Yu He's lecture, I changed a sentence to "There is no limit to learning, and I am willing to make a boat" according to my own learning experience. I have a deep understanding.

You should read the two speeches I mentioned first, especially Yu's English Learning and Life Struggle, Rising in Disappointment and the Revolution of Learning Methods.

The workbooks I use are "May 3rd" and "Three-year Simulation of Five-year College Entrance Examination". Fill in the blanks with basic knowledge first, then do examples, and finally do exercises.

4. Finally, we should do "one preview and four reviews", focus on preview before class, and do small exercises in advance after class. Just draw a few question marks if you don't understand. Review: the first is to review what you will do in class as you did for the first time (many students can't do this, but if you can, you will definitely catch up with and surpass your classmates); The second is to recall the contents of the class between classes, also called movies; The third is good exercise books and homework, so you must study. Fourth, spend about three minutes before going to bed to recall all the contents learned that day. One preview+four review is the magic weapon for your study.

Note: The final "one preview and four reviews" is applicable to all subjects.

I wish you progress in your study!
