polop26 It is thanks to Bryan that i was able to raise my A math grade from D7to A2, and E Math from C6 to A1for my O levels. He is a very dedicated teacher who always answers my questions at anytime. He even replied my whatsapp messages at 1 am. The material he provides is very useful, such as tailor-made cheat sheets and question papers. Thanks Bryan, could never have done it without your help!
