Next, we will talk about practical problems. The most important thing in practical problems is that the teacher must do the corresponding exercises in time after finishing the new class. Attention: timely! As for two exercise books, it is enough, but more will do harm to people. Always adhere to one principle: do fewer questions but be precise. Even if a problem is not worked out for 5 hours, it is worth it!
In this process, it takes time to improve your grades and abilities. If you encounter setbacks or fail in the exam, you must persist. As long as you persist, you will succeed!
There is also the need to make full use of the network, such as Baidu's "Know".
That's how I got here. I did it through these methods, and my grades will gradually improve. I did very well in math in the final exam this semester!
Wish you success!
