Once again, there is chemistry (Jiangsu Education Edition): there are only two required books, and there are five optional courses if it is correct. Generally, students who choose a science course will not study it, and the others will be arranged by the school, because the elective part of the college entrance examination is optional, and all schools will study these three books (elective parts) of organic chemistry. Other studies are also outlined.
Last English (Beijing Normal University): I don't know why your textbook is from Beijing Normal University, but we studied the People's Education Edition, which may be something like this. One to five is compulsory, and six to ten is optional. If the school has enough time, we will finish all the studies. If we don't have time, we will browse them, or if we think they are not important, we will skip some of them.
