The position and subject characteristics of mathematics in agricultural unified examination;

In the postgraduate entrance examination, candidates can choose mathematics and chemistry according to their own learning foundation and the need of volunteering for research work. Compared with chemistry, mathematics has fewer knowledge points but is more flexible. Mathematics is a basic subject used in all kinds of research, and it is an indispensable knowledge system in the process of preliminary experimental design, scheme selection, data analysis, result inference, model establishment and paper completion. In addition, learning mathematics can exercise logical reasoning ability, make people form a rigorous and abstract way of thinking, and is conducive to thinking and solving problems.

Comparison between the past and the present:

After the unified agricultural examination, agricultural colleges and universities will no longer freely choose the source of examination questions, but will take the textbooks and examination modes designated by previous postgraduate entrance examinations of China Agricultural University as the standard. In view of the different teaching contents and levels in agricultural colleges and universities around the country, the overall difficulty is lower than before, but at the same time, the investigation will be more flexible and diverse.
