But for the record, 70 1 is math, not chemistry.

The content of the 702 chemistry (agriculture) exam will be more difficult than 3 15 chemistry (agriculture).

The content of the 702 chemistry exam should be read comprehensively, and the bibliography should be reviewed:

General Chemistry (3rd Edition) edited by Zhao Shiduo, China Agricultural University Press.

A Brief Course of Quantitative Analysis (2nd Edition) edited by Zhao Shiduo, China Agricultural University Press.

Organic Chemistry (4th Edition) edited by Wang Xiaolan, Higher Education Press.

Chemistry Review Guidance and Exercise Analysis, edited by Zhao Shiduo, Zhou Le and Zhang Shusheng, China Agricultural University Press.
