Let me talk about my experience. Biology is actually very simple. I study biology. I should concentrate on listening to the teacher in every class and understand what he means. Because I follow the teacher's thoughts closely, I basically don't talk in class and have no time. My biology teacher likes to deliberately draw some wrong conclusions in class, and some students who don't understand follow suit, and then the teacher points it out. This makes every student develop a rigorous thinking habit and will not be easily brought into the circle by him. When he occasionally gossips, I just listen and memorize what I just learned. I review for a few minutes after class. When I do my homework at night, I will quickly recall it, then turn over the books quickly, and then do my homework. If you don't understand, you must ask clearly. I have a 38-set Tian Li Biological Volume, which I bought myself, synchronized by sections and specially made during review. I wrote the new things I met in a book with a red pen. In fact, senior high school biology focuses on senior one and senior two, and senior three books are equivalent to expansion and review. You must know the back of the two books in Senior One and Senior Two by heart. No exam can beat you. Sincere words, hope to adopt!
