Students and parents love our maths help

But don't take our word for it…

Trishna Pillai

Higher 1 maths student, Woodlands, Singapore

"My maths teacher told me that I am not going to make it in the A-level exam because my marks at school were quite bad. So, I tried all types of maths help I could get, tutors, YouTube, test prep books. StudyPug is the best of all! The results were great and even my teacher was surprised. You are my study buddy for the A-level exam."

Carson E.

parent

When we saw our son's grades we looked online for a convenient, affordable and effective solution. StudyPug has been a great investment.

Jason G.

high school senior

This website saved my butt last semester. I am using it againthis semester. Dennis is the best online tutor... I also like that I can watch videos over and over until I really understand the concept. If you want to save time, sign up...it's only ten bucks and it saved me hours of study time. Thanks, Dennis!
