1. The Institute of Systems of China Academy of Sciences is a subordinate institute of the Institute of Mathematics and Systems Science of China Academy of Sciences. If you enroll students, you will enroll students in the name of the hospital. However, there are also schools of mathematical sciences of the Chinese Academy of Sciences that also recruit graduate students.

2. There are many applicants for Chinese Academy of Sciences. It can be said that most of them, only a few have been admitted, and there are so many applicants, but I heard that they are admitted every year. For example, I entered one with my classmates and submitted one. There are only a few points and a high score in the initial examination of the Chinese Academy of Sciences, and the real questions can be found online (you can go to the doctoral mathematics forum to ask). If you have a good foundation, you will get an organic exam. As for the enrollment brochure, I don't know if it is available on the website of the system. It seems not available.

3. If you want to continue your Ph.D., even if you are admitted, you can take the PhD transfer exam in the second year of graduate school. If you pass, you will continue to study PhD. Most teachers welcome students to continue to study PhD.

It seems that when registering, you just need to determine the direction. You don't have to choose a tutor, but you have to go in for a second interview or research.

I wish you a smooth postgraduate entrance examination and become the first!

Hey, this score is not easy ~ ~ ~

Supplementary answer: The papers of Institute of Mathematics and Institute of Systems of Chinese Academy of Sciences are the same.

In fact, my senior who was admitted to the school got very good grades. She originally prepared for the postgraduate entrance examination, but later she took it for special reasons. After only a few months of preparation, I was admitted.

Chinese Academy of Sciences feels it is very difficult to take the exam, and I don't know the real situation, hehe. I wanted to take the exam myself, but after weighing it, I gave up. But I have some questions from my sister who is studying in the system. If you want, leave an email.

PS: Can you give points? Thank you.
