Zhang Yu is good at digging up concepts, and he advocates tracing back to the source. How did this thing come from and what does it have to do with reality? Students with a good foundation are not short of training in question types, and listening to teacher Zhang Yu's class will make them integrate.

But students with poor foundation sound cool, but without a certain foundation to explore conceptual methods in depth, knowledge points will be easily forgotten like castles in the air, and all theories come from practice.

Attach importance to teaching materials:

The first step in math review is to read the textbook. When reviewing, I also saw that some students started with counseling books, but after more than a month, they had to return to textbooks, which not only wasted time, but also made them impetuous. Textbooks are the foundation and knowledge that must be paid attention to in mathematics review.

So we must grasp and make good use of it. When you have mastered the basic theorems, principles and formulas through the textbook, you should do the questions at the back of the textbook carefully, which is to test your mastery of the basics. When you encounter problems that you can't do or do wrong, you must really analyze and summarize them.
