How about Harbin Jingxuetang cram school? Ask the seniors and sisters who make up classes there to answer.

There is nothing to say about the quality of school teaching. Maybe I belong to this kind of student who listens to the teacher. I haven't learned math well since high school, thanks to my mother who taught me to teachers in elite schools. My math scores have made great progress. Now senior three, I have passed every exam 120. This is progress for me. Anyway, I think teachers are responsible! I only got 60 points in the exam!
