The difficulties and emphases of senior one are divided into A~E grades according to different grades (from high to low), and different grades require different emphases. As far as I know, E-level students only need to master calculus. I studied a-level, so tell me, I don't know anything else.

Functional part. 24 kinds of limits, existence conditions. Important limit, high-order equivalence and other concepts. The concept of function continuity and discontinuity.

As long as the mean value theorem is not low in the examination requirements of mathematics department, it is enough to master the example methods in the book.

The emphasis of calculus is integration, and the difficulty of integration lies in method of substitution and integration by parts.

Space geometry assessment requirements are not high, just master the example method.

Learning advanced mathematics well depends on doing more, especially things like calculus. Hua and Su also took more than 20,000 courses to reach their peak!
