It's not too late to be bad at math in senior one. If you only rely on 40 to 50 points, those small questions must be wrong. Now you should focus on choosing and filling in the blanks, and do more type exercises. If you can do a small problem well, memorizing a few formulas can make a big problem get 20 to 30 points. It's easy for you to pass 90. Even if you still can't do a big question well, there will always be a review teacher who will hold all the big questions in the college entrance examination once or twice, but there are too many knowledge points in the small questions.
