There are compulsory 5 and elective courses in Chinese and English, and compulsory 3 and elective courses in mathematics in the next semester of Senior Two. You have a required course in biology. 3. Physics and chemistry are both optional courses. Where are you from? Elective courses vary from province to province. I don't know Anhui, but I'm from Guangdong. Last semester, math required course 3 was 2- 1, and Chinese required course 5 was Yuan Qu of Tang poetry and Song poetry, but the publishing houses of Chinese were different. English is different from your publishing house, but mine is People's Education Edition, compulsory 5, elective 6. Physical chemistry is not clear, and the progress of each province is different. Mine is the Guangdong version of the textbook; Biology is a compulsory course; Politics is a compulsory course. 3. Cultural life; History is compulsory three; Geography is also compulsory.
