Quora, via a kind Richard Askey email:

You are in Mordor now and way closer to Mount Doom.
There is suddenly so much less free time and everyone including the aunt of your neighbor kid’s cousin start to ask you how many years you have till “High School Entrance Exam”.

Now the main subjects are:
Chinese
Math
English
Science (Physics, Chemistry, Biology)
Politics

Secondary subjects are:
Physics
Information Technology
Music
Art
Moral training (Apologize for my inability to properly translate.. You are generally taught how to behave, to love the Party, etc)

At the same time as an excellent student (score high is usually sufficient to earn that title), you will be taking National Math/Science Olympics Competition and spend loads of time on high school maths problems.

If unfortunately you don’t have a decent grade ensuring a good high school, you will have to spend much time on home tutorials apart from school.

I was of the second category, and spent 8 hours per week on Chinese, Math and Science, later English too.
