I know this! Beijing Foreign Studies University does. It's the Examiner College. There are two campuses, one in the headquarters and the other in Xiangshan branch. Xiangshan branch is also in the same place. The headquarters is a little far away, so I have been to both places and I feel ok. Mainly by our own efforts.

There is an old teachers' association outside the North Gate, which is now renamed as New Ying Da. It specializes in self-study training. The conditions are average. There are few classrooms, and some teachers are too ordinary. I personally don't like it there.

In fact, people who choose to take the self-study exam are persistent, so as long as they have the heart, they will certainly be admitted.
