It doesn't matter how many books you use to learn math well, the key is implementation. Take the teacher's homework and exams seriously and sum up the reasons why you can't do it or do it wrong (don't make excuses! The excuse is easy to find, but it won't help you. Accumulate classic good questions in a down-to-earth manner, and mastering a method you have seen is king. Besides, think about it. After all, the exam questions come from textbooks. It's really difficult, and there won't be any particularly strange problems. Even if there is, I won't be afraid, because everyone is the same. What really opens the gap is the methods and models that have dealt with everyone. As for "I am stupid and slow to reflect", it doesn't matter. It is often an honest man who laughs last, not a wise man.

Physics? I suggest you read more difficult books, such as competition books. I think the key to physics is clear thinking. It helps to look at difficult things, even if you can't. Look at other people's thinking and think clearly, and you will make progress over time.

Hehe, anyway, I am also one of the top ten students in the senior high school entrance examination in the city, and I should have rich experience.
