Brain is 50 dollars / 2 hrs of lesson and 60/ 2 hrs of lesson for one on one. Prices don't change on weekends or holidays or anything like that.
I went there and got 97 in English Advanced and my entire NSB class this year all scored band 6s.
2 97s, 2 96s, 3 95s + a couple of 92s and 91s!
The Brain is definitely a good Maths alternative. I know their head of maths Nathan is about to come out with a new textbook, so things are really rolling there.
The teachers there are really experienced but also down to earth people, which is something Dr. Du doesn't have lol...
