This problem is related to the training plan of the school itself, and different schools are different. Freshmen generally study transitional courses in the last semester to link up with senior high school knowledge, so that freshmen can integrate as soon as possible and find the most suitable state of university life when their studies are not too heavy. Some schools will appropriately insert a professional course (usually local anatomy), and the transitional courses are generally medical physics, medical chemistry, advanced mathematics, introduction to medicine, college Chinese and so on. However, there is still a difference between organic chemistry and medical chemistry. Medical chemistry contains organic content and inorganic content, which is relatively simple. Some basic chemical knowledge is closely related to high school chemistry. Physiology and biochemistry (specialized course) is the chemistry that clinical medical students really need to study in their sophomore year.
