I study literature. I feel that liberal arts mathematics in our high school is much simpler. At first, there was very little to learn. It seems that the mathematics of science in senior three has infiltrated the advanced mathematics of some universities, and then it is not so difficult to work out the same knowledge points. In the case of simple questions, it is very possible to score 130 in the college entrance examination. My feeling is that you can almost study liberal arts mathematics as carefully as possible. In addition, by the way, the situation may be different in different regions. I'm talking about Hebei.
