A: I think the most difficult thing is mathematics, because Chinese can be improved through reading and accumulation, English can be improved through reading and memory, and mathematics can only be improved through practice.

In fact, the reason why mathematics is difficult is the inflexible use of mathematical formulas. Only mathematical formulas can't be used flexibly, so it is naturally difficult to improve math scores. In science, formulas are only the most fundamental. Many students know that formulas are very important, but they don't know that it is not enough to just remember formulas, but they need to be used flexibly. This is one of the reasons why some students seem to study hard, but their final grades are not ideal.
