The first semester of freshman year is ok. I studied inorganic and analytical chemistry with a high school background, and I was careful in class, at least I could learn it. In the second semester, I learned a lot of organic chemistry, and I focused on reviewing the final exam, but my score was just passing. Sophomore physical chemistry and chemical engineering principles are even more troublesome. Class is like listening to a gobbledygook. You can't understand it after class, but you have to wait for death. It's really the last college entrance examination.
There are many experimental classes in this major, which is quite interesting. Doing experiments by yourself will be very fulfilling. If the result is not good, you will want to keep doing it until you get the desired result, so sometimes you will do the experiment late. This is a kind of pain and happiness. There are other more painful things. Our experimental teacher asked us to write the experimental report by hand, including the experimental purpose, experimental steps, result analysis, experimental conclusion and so on. When doing the experiment, we have to write three or four pieces of paper. Every time we finish the experiment, we feel that we are back in high school.
In addition to basic theory courses and experimental courses, we also have specialized courses, starting from junior year. Compared with boring basic theory courses, specialized courses are much more interesting. Listen to the teacher explain various technological processes, manufacturing principles, etc. We find that all kinds of common little things used in life are very learned. Because of the connection with life, all kinds of courses are not so difficult to learn and feel better and better.
