hi i currently attend there
it boosted my grades a lot, from 60% averages to 90% averages, but also it is not for everyone
their teaching style is explain theory, teacher goes through example qns, then u have a go at practise qns and then homework on the thing
most teachers are quite good at ensuring u memorise concepts and their strict homework policies force u to learn the content & take tutpring seriously
they also offer a whole bank of past paper resources for yr11-12 students
IM NOT NGO N SONS SPONSORED LOL i am promoting them so much omg..
