Testimonials

Real Students, Real Success!

I joined Glenn in July 2024. He has pulled up my A and Emath grades from E8 to a A1 in O-levels for both subjects in just 4 months, on top of my chem from F9 to B3. He is patient and motivated me to do my best in many ways. I am very grateful to him and his engaging and fruitful classes. Thank you Glenn.

I joined Glenn on the 3rd of October 2022 which is around 2 weeks before o’levels. Having scored a C6 in my Amath and a B4 in science (chem,bio) for prelims, I was unsure if I would be able to catch up with all the needed content in just 2 weeks. However, it was a great decision joining Glenn, he not only improved my grade to a B3 in Amath and an A1 in my science for o’level in just a short period of time but he also motivated and encouraged me throughout the o’level period. Without Glenn’s help, I would never imagine getting such grades. Thank you Glenn.

If you need help with any secondary school topics, Glenn is the man you’re looking for. I went from an F9 in Combined Science Physics & Chemistry at the end of Sec 3 to an A1 for O Levels because of him. And I didn’t even have to put in much extra effort. He not only guided me but ensured that I understood the foundation of every topic he taught, which enabled me to build a strong understanding of the subject matter. Subsequently, I absorbed everything much more easily. Find out for yourself.

Glenn is a passionate teacher who is willing to help his students ace their exams. I first joined Glenn’s tuition when I was secondary 1 and was failing my math and science. However, after 3 years of hard work with Glenn, I aced my N Level exams with a raw score of 5points. With his help, I was able to get A1 for both my math and science. Thank you Glenn for helping me build up my confidence and achieve the results that I never would have been able to without your help
