1. Listen carefully in class. The most important thing is to concentrate in class, listen carefully to the teacher's explanation, and ask questions in time if you don't understand.
2. Review exercises after class. Learning can not only stay in the state of understanding in class, but also take time to review after class.
3. Wrong title book. Notebooks mainly record wrong topics and topics you think are better.
4. practice in blocks. The average student's poor math performance may be due to a bad piece. You can find more topics in this area and practice more.
