Never do a difficult problem. If there is no division of arts and sciences, we should pay attention to the accumulation of basics, pay attention to the examples in the textbook, and do the examples in the book well! There is a big gap in general math exams. If your foundation is not very good, the example in the textbook is a good teacher. Do it several times, understand why you answer like this, and then try to think from other angles, so that the breadth of thinking can be improved accordingly!

Everything is perseverance!

Wish you success!
