It's up to you to do well in the exam. If you are interested in a certain direction, you won't feel tired when you study, and it will be much smoother in the future. Lanzhou University is a cost-effective school. Because it is remote, its score is lower than that of the eastern universities, but its strength cannot be underestimated.
I checked the exam subjects for you:
(1)101ideological and political theory
②20 1 English 1
③6 15 biochemistry or 6 16 cell biology.
④8 18 ecology (including individual ecology, population ecology, community ecology and ecosystem ecology)
Retest written test subjects: general botany or advanced mathematics.
I will have an exam next year, so I understand your feelings very well. Let's cheer together and wish you good luck!
