Pay attention to the method when learning:
1, on this basis, master the basic knowledge;
2. Do a good job in knowledge points and sort out difficulties;
3. Make a mind map of each unit to ensure that you master book knowledge;
4. Do more hands-on verification of mathematical formulas, and get better results through practice than rote memorization;
5, do more questions, not brush questions, but see why the teacher wants to ask questions, what knowledge points he wants to test, and what knowledge points can be combined.
