Haha, you are a chemistry major. I am a chemical engineer. Look at your problem. You took the engineering exam in the postgraduate entrance examination, and you took two more math exams. Specialized courses include chemical engineering principles, organic chemistry and physical chemistry.

Pick what you want and choose what you are best at. Personally, I suggest physical chemistry, and organic chemistry is also acceptable.

The principle of chemical engineering seems simple, but the problem is too complicated to do it all.

Organic chemistry is difficult to remember, mainly because there are too many knowledge points, and they are all based on mechanism. If you have a better understanding of the reaction mechanism, you can also choose this one, because everything in organic chemistry depends on the mechanism. As long as you remember the mechanism, there will be no problem.

Physical chemistry is difficult to learn, but once you learn it, it's easy, because it's not easy to learn at first, but it's easy after you get in, because his questions are fixed. As long as you do more questions, you will find that physical chemistry is actually several questions.

Let me tell you about the research direction. In fact, this is not decided before the exam, but mainly when you choose a tutor after the initial exam. Because your tutor's research direction is different, you can only choose your own research direction if you choose your tutor.

Finally, I wish you success in the postgraduate entrance examination. The engineering score is not high. As long as you work hard, it will be easy to take the exam. Remember to add points if you are admitted! !
