Mathematics is a compulsory course for 1-5 and an elective course for 2- 1 to 2-3. In addition, two of the four books, such as 4- 1, are selected. General schools choose matrix and polar coordinates. Inequality will not be selected by the school, and geometry will not be selected by the school.
I take 3-4 and 3-5 as three optional courses in physics, but it's hard to say. Some schools go 3-3, 3-5, and all combinations are possible.
Chemical elective course * * * two books must choose material structure and properties, because this kind of topic is to send sub-topics. . On the contrary, experimental chemistry is too difficult to get high marks. Of course, there are also some particularly tough schools that will learn some of the contents of this book, but the structure and nature of the materials are compulsory for every school.
