It's really crucial to apply for art majors now. I recommend a school for you, which is a local school in Chengdu, Chengdu Paitou Art Training School. One of my classmates is training there. He scored more than 300 points this year, much higher than the undergraduate line. I envy him. I know I will go there for training. He said that the facilities there are complete, and the teachers are all Ishikawa Chuanyin. Can have a look, the place seems to be in the TV tower, you can find it online! I wish you good grades!
