1, in the review stage of senior three, it's best to prepare a mistake book (thick) to copy the daily mistakes on it and then do it again. The teacher will add some extra-curricular knowledge points, or theorems, or formulas, and it is best to write them in this book, so as not to be in a hurry when rummaging through them in the future.

2. I think there is another point in math: I will do it lightly and always make some small mistakes that I shouldn't make. Such mistakes are the most troublesome. Therefore, we should always pay attention to it in our usual study. Exercise your mind.

3. The improvement of mathematics is a slow process. Don't lose heart just because you failed several exams. Cheer yourself up: quantitative change has not yet reached qualitative change, as long as you persist for a while, you will succeed!

Remember not to compare horizontally with others, but vertically with yourself. Who cares about others as long as you make progress again and again?

The above is my experience, I hope it will help you!
