I am an undergraduate student at the University of Colombo studying Mathes Special. I have 5 years of experience teaching both O/L & A/L students. All that students get high marks in their exams & one of them become district 7th in Kurunegala district last year(2020) by Physical Stream. I am happy to say that so far no one who participated has failed. Get an Olympiad Merit rank by Mathes in 2018. . You can choose the time whenever you want.
