(1) biochemistry majors, except for a few liberal arts majors that are partial to management (such majors are not very good, so there is no need to ask), all of them take math exams. The content and required depth of Math II is not as deep as that of Math II, so we can consider crossing over to biochemistry major. The majors of Math II are mainly chemical engineering, chemistry, biology and environment. Therefore, you can also consider other majors in this field, which are highly relevant. Specialized courses are generally not too difficult and will not increase the burden for your subsequent review of specialized courses.
(2) Biochemical major, Tianjin University is good. Not only 2 1 1, but also 985. Tianda Chemical Industry is one of the leading universities in China, so it would be better if you are willing to jump in the direction of chemical industry. About the bibliography—
Chemical engineering, chemical technology, industrial catalysis, environmental chemistry, etc. Their major is physical chemistry or chemical engineering principles. Physical Chemistry is Physical Chemistry published by Higher Education Press (edited by Wang Zhenglie and others). ), and the book Principles of Chemical Engineering is Principles of Chemical Engineering published by Tianjin University Press (edited by Xia Qing and others). ).
Good luck with your review!
