Multiple choice questions require a large amount of calculation, and the latter three requirements have a certain foundation. The penultimate one is more flexible, and the last one is more difficult. The second big problem (solid geometry) is more difficult, and the fourth big problem, the second problem, is more flexible and needs a lot of calculation. Compared with last year, the last two big questions have higher thinking content and slightly simplified operation. The overall difficulty is greater, but it is slightly simpler than last year.
