I didn't like it much at all tbh I went there for 2 weeks and just left. Classes are quite unstructured, and he's pretty hard to understand, even for an asian tutor. I've been to a lot of well known asian tutors and I can understand them all fine- him however, that's a different story. Also a lot of time seems to be wasted, and if you're stuck in a class of talkative kids ur pretty much screwed. That's why I left, because he can't control them. And they just eat and talk during the test time since it doesn't really matter anyway.
Would recommend Dr Du or Ace for phys/chem tutoring.
