I think Tongji's textbooks are a bit difficult. I didn't learn much. It's better to use that in math. If it's math three, I don't think it's necessary. Besides, when you study, you use the NPC version. You are familiar with the NPC version of the textbook, so getting started will be easier. If you start reading new textbooks now, you may be a little unaccustomed. I also bought Tongji textbooks when I took the postgraduate entrance examination, but I didn't read them after turning over a few pages. The teacher also said it was unnecessary, so I used the textbook compiled by our school. Read the textbook carefully twice, do exercises after class twice, and then do real questions, review the whole book, simulation questions and so on!

Therefore, I think you should take a good look and do a good job in the teaching materials of the National People's Congress! After all, the textbook is not about how much you read, but that you will be useful if you read well! Hehe ... Come on!
