Everyone has different learning ability. You should compare yourself, not others. Make up for what is not done first. Listen carefully in class and don't leave school without sleeping. I suggest you make a good study plan, set a good goal, talk about learning methods, and constantly improve learning methods to improve learning efficiency. You can make a "correction book" and write down your usual mistakes to facilitate review and improve review efficiency. Regularly organize the notes of various subjects.

Now you are only the second grade, don't worry too much, the second grade is very important, don't relax! Give yourself some confidence and you can learn well.

Remember one sentence: no pains, no gains!
