Students should learn to find loopholes in their own subjects, mainly in preview. Students' learning goals are clear, their attention will be focused and their class efficiency will be high. In addition to previewing, doing problems is also a good way to find loopholes.

2. Doing more questions does not mean improving scores. Only by filling more loopholes can the score be improved:

There are thousands of questions, and we can't finish them. The purpose of doing the problem is to master and consolidate the knowledge points. If you have mastered it, there is no need to do it again. Students should spend their time filling in loopholes, and they should also attach great importance to preview.

3. The key to implementation is detection and repetition:

Implementation is the last word. The best way to see how effective you are is to test it. If there is no problem with repeated testing, then the vulnerability will not go up. Filling the loopholes cannot be solved once or twice, and it needs some repetition.

4. "Better late than never" and "save for a rainy day":

After the exam, the teacher analyzes the wrong questions and the reasons for losing points one by one-looking for loopholes; Formulate practical and effective improvement measures-find a way; Strengthen special training in a targeted manner-fill the loopholes. Sometimes it's better late than never, so we should "plan ahead". Write down the problems in your study every day and solve them. The mock exam before the exam is also a good method.
