2. Listen carefully in class. If you doze off, stand up and listen. Never mind what students think, it is important to learn the content of the class well by yourself.
3. Review after class. If you don't understand in class, ask the teacher in time between classes. Today's homework was finished that day.
Preview, study and review are well done, and learning will make rapid progress.
In addition, do more sets of simulation questions before the exam and finish them within the specified time. Ask the teacher for the wrong questions and understand them thoroughly. Don't let go of a topic you don't understand easily, because if you give up more topics, you will accumulate a lot of things you don't understand.
