Personally, I think physics is good, but math is difficult (maybe it's because I'm not good at math, which varies from person to person ~)

Recommend the creatures of the century gold list, the knowledge points are very detailed and the explanations are quite clear.

Generally speaking, I think the series of the Century Gold List is not bad, much better than the optimized design. If I am a graduating class, I strongly recommend the three-year simulation of the five-year college entrance examination, especially Chinese, which is very useful.
