What exactly does high school 3+X mean?
3+X policy, "3" refers to mathematics, Chinese and English (it seems that liberal arts mathematics is simpler than science mathematics), "X" refers to comprehensive management or literature, and comprehensive management is biochemical physics; Literature synthesis is historical geography and politics. I probably looked at the paper, and it seemed that all the questions were completely mixed up. For example, the first question is physics, and the second question becomes chemistry.
