Anyway, come on and do your best.
Regarding the second question, chemical technology belongs to engineering, and you can get the result immediately by looking it up online. Generally speaking, chemical industry is good, such as Tianda, Dalian Institute of Technology, South China Institute of Technology, Beihua, Zhongnan and so on.
Analysis belongs to science, so you don't need to take a math test. Wuhan University, Hunan University and other analyses are all good.
General engineering subjects are Math II and Physical Chemistry. (If it's chemical engineering, the applied chemistry of engineering is generally math plus organic. If you take analysis, it is science. Some schools will take a comprehensive examination like Wu Da, that is, they will take all four basic courses, some will take physical chemistry plus organic, and some will take physical chemistry plus instrumental analysis. It depends on the school.
