I don't think there is a better way to say the two, mainly depending on what suits you.

Chalk:

According to the reference materials, I think the four sets of real test papers before subject 1 and subject 2 are quite good. I bought it before the exam, which is a good simulation of my academic performance. It seems that I didn't have much time to prepare, so I bought it directly to do the problem.

In addition, some of my classmates bought their textbooks, and they felt focused, clear in logic, fresh in color, very eye-catching and comfortable to touch. Perfect for learning for the first time. However, the disadvantage seems to be a bit expensive, a set of several hundred dollars.

However, the process of chalk is very careful. My review process completely followed the teacher's ideas over there. It took me a month to do the real problem seriously and passed 80+. After two years, I can't remember the specific scores, but the chalk course is really good and the handouts are very detailed!

Zhonggong:

When preparing for the exam in 2020, I bought a set of Chinese public materials in Yiyu, including textbooks for subjects 1-3, as well as supporting real questions, 6 books and interview tips. It cost about 90 yuan in total, but the textbooks were rather lengthy, so the textbooks were only subject 1 and subject 3, and I studied and practiced completely with real questions. The real question of subject 2 is really yyds, which can completely cover all test sites and get similar original questions.

During the interview, the Chinese lecturer did a good job, and there were many teachers' classes at a certain station, which were completely covered.
