I was a student of the owner of pop tutoring for all of high school for math, I went to prep classes that were disappointing (size 3-4 people)as well as diploma prep. he was my personal tutor and when I told him I wanted to do my math 30-1 diploma prep else where, he text me in the middle of class and quit, it was the last 3 weeks of my math class. he quit because I wasn't going to his diploma prep. He said "maybe the company wasn't for me." Terrible, disorganized, don't recommend.
