You'd better ask the teacher to make it up at the weekend, and then follow the teacher's steps to buy a set of relatively basic exercise papers, instead of buying a comprehensive one, that is, compulsory 1, 2, 3, 4, 5, which is a separate one.
It is the most important thing to insist on making one piece every day. You must stick to it. Even if you really don't have time or can't do it, you should persist in doing math if you only do half a piece every day, which will gradually form a sense of mathematics. If you can't, study the answer yourself or ask the teacher, preferably because asking the teacher can understand the teacher's thinking and teach you how to analyze.
The above paragraph is the most important, and then there are some good habits. Class time is very important. You should take notes, write down the typical examples and mistakes the teacher said, and finish them after class.
You should have a wrong problem book, not copy every problem, but also classify your wrong problems, such as trigonometric function, inequality, geometric analysis and so on. In this way, when you put the questions together, you will find that many things are similar, such as the steps to solve the problem, the knowledge points used, or eventually they will be transformed into some form and accumulated slowly, and soon you will find the rules and methods to answer the questions.
Liberal arts mathematics is relatively basic, so there is nothing particularly strange. It's really hard not to get into trouble, because it will be difficult if you have a bad foundation, which will affect your confidence in mathematics. You can find some simple basic questions to build your confidence and interest. In fact, there is no way to do more in mathematics. Really, sea tactics should be the only way for the college entrance examination now. On this basis, it is good to sum up and think more. It will be more effective and the teacher will repeat it in another round of review. Don't worry too much. Now you are doing well in the new class in the second day of junior high school, and you will consolidate your foundation after class. It's no problem to get a score of 120 in the college entrance examination. My math score in grade one of senior high school is basically 50. . . Now I can get 100 in the exam, hehe, work hard, come on, don't give up, I will do it.
Also, 5.3 that book is very good, but it is suitable for a round of review. Don't do that for the time being, it is very difficult.
I hope my experience can help you ~
