2. If you want to take notes well, you must preview them first! High school teachers won't wait for you to write notes. Preview before class helps to avoid being in a hurry!
3. Remember the teacher's skills in doing examples in class, not the specific steps (unless you don't know)
If you have a bad memory, you can sort out your notes immediately after class, and if you have a good memory, you can leave a chapter to sort it out (I am! ), but not more than a week. Don't do problems every Sunday, pay attention to sorting out your notes and sort them out several times. If you don't understand something, you will naturally understand it.
The notes are complete, but you don't know how to understand them. You can do the problem first, and then compare the notes to see how the problem is solved. Don't be greedy, read chapter by chapter, and don't owe money!
6. When you understand something on weekdays, you can supplement it with loose-leaf paper and insert it in the corresponding position. This is why you use loose-leaf books!
