I think the most important thing is basic knowledge. Don't think about how fast their math scores can improve. Your greatest expectation is to let them get the points they deserve. Every class aims at training and consolidating one's basic knowledge. Don't give them too difficult questions. At the beginning, try to do something simple to improve your confidence in mathematics and gradually increase the difficulty. Of course, no one knows what the final result will be, and who knows whether they will play their normal level.

There is also learning the syllabus and the annual higher vocational examination questions, finding out the types of questions for training, teaching them how to solve problems, and letting them cope with changes with constant changes.
