Work independently and concentrate in class.
Don't be lazy in doing your homework, the effect of doing it yourself will be doubled! Only by thinking independently can you concentrate in class. When you encounter something you don't understand, the teacher's explanation becomes the most valuable resource.
Listen to the lecture first, supplemented by notes.
When the teacher is talking about the topic, don't recite it in a hurry. Understanding is the key. If you do it yourself after class, you may find that you don't have any ideas, but you haven't absorbed the wisdom of the teacher yet.
The wrong set of questions is a treasure house of wisdom.
Don't be discouraged when you meet the wrong questions. Establishing the wrong problem set is the ladder of progress. Record the thinking of solving problems, analyze the causes of mistakes and avoid repeating the same mistakes. High school has accumulated more than a dozen books, and the college entrance examination has gained a lot.
Proficient in formulas and worry-free in solving problems
Not familiar with the formula? Don't worry! Mastering the application is more important than rote learning. Face the problem directly and quickly determine the required formula, and solving the problem is half the battle.
Help others and learn efficiently.
Don't stick to the problem. Asking for advice from classmates or teachers and looking at problems from another angle often get twice the result with half the effort. High school is precious. Don't let problems hold you back.
