About Mr. Kasun Perera

Mathematics Teacher · B.Sc. (Hons), PGDE

Hello, I'm Kasun Perera

Mathematics made clear

I have been teaching mathematics for more than 12 years, in classrooms and online.

My lessons start from the idea behind each topic, then move to exam-style practice. Every student gets marked work back with comments, and parents see progress every month.

Outside the classroom I write model papers and run free revision sessions before every national exam.
