The book "Complete Interpretation of Middle School Textbooks" is good (I have been using it for three years in junior high school 1. At first, I was not good at math. Indeed, this book is very helpful. If you buy it, don't just do it because there are not many questions. Look at the examples and explanations! There are some skills in the book)
1, in fact, grasping the third grade does not affect the senior high school entrance examination, and the mid-term examination questions are not difficult. You must listen to the class well (force yourself to concentrate)! It is very important that the effect of cram school can not be achieved (it is best to attend cram school)
2, to have information, not too many questions, not too many questions (Xue Jinxing's "Complete Solution of Middle School Textbooks" I strongly recommend it! I passed 1 14 in the senior high school entrance examination, and I got a good grade in junior high school mathematics and a good competition. Of course, I got full marks.)
3, you can pass if you can't lift it, but you must understand the knowledge you don't understand!
4, interest is very important, and speaking in class can quickly enhance interest. The teacher is glad that your mood has also been mentioned.
As for the moving point problem you mentioned, it is a difficult problem. The conditions of the topic must be remembered. If there is no picture in the picture, draw it and mark it!
Concentrate on thinking, even if you don't work it out, when the teacher explains it, you will suddenly realize what you didn't understand when you did this problem, as well as your weak knowledge points.
Move a point, the senior high school entrance examination will only produce a big question, or fill in the blanks (although this is difficult, it is not the point! The combination of quadratic function and circle in the coordinate system next semester is the key and difficult point. There will be big questions in every senior high school entrance examination, most of which are the last questions)
Think about some questions, then listen to the teacher carefully, learn slowly and go your own way!
Hehe, come on
