I want to take the postgraduate entrance examination in library science of Chinese Academy of Sciences, but I don't know how difficult it is, and it is interdisciplinary. I really want to take the exam. You are so confusing! I really want to take the exam, but I'm not very confident.

If you really want to take the exam, you have to take it no matter how difficult it is. As far as review is concerned, every school should review carefully, especially the better schools. If you are not serious, you can't get in.

Personally, the difficulty of Chinese Academy of Sciences is the most difficult one in library science.

I really want to take the exam. If not, you will regret it. So prepare carefully and don't worry so much.
