Testimonials
Thank you very much for helping De Li with his Maths. He got a 6 (7 being the highest grade) so we’re all very happy and relieved. Thank you! This is amazing.
Min, Mother of De Li, Hwa Chong International, IB AA Higher level Mathematics, result released on 2 Jan 2024.
Mr. John is an excellent math tutor with a great command over the subject. He has by far been the best math teacher I've had. During my final year in Global Indian International School Singapore, I was failing in math. However, Mr John brought me from failing to a ‘7’ (highest grade in IB diploma courses) in just 8 months. His teaching methodology stems from his passion for math and encourages his students to enjoy the subject rather than see it as just a subject they are required to get a good grade in. I am very grateful to Mr. John as his efforts have been one of the fundamental building blocks towards where I stand today. Thank You,
Ishak, Global Indian International School, International Baccalaureate (IB Diploma) AA HL Mathematics.
Beyond his academic excellence, Mr Chang fostered a genuine sense of connection during his A-math lessons. His style of teaching was very personalised and he made an effort to get to know me better so that he could offer lessons that were both fascinating and engaging. He not only prepared worksheets that targeted my weaknesses in maths but also went beyond and introduced interesting facts about math that intrigued me greatly. This one-on-one focus became an invaluable asset in my preparation for my GCSE O level Exams and continues to fuel my love for maths. Under Mr Chang's guidance, I managed to be confident in my examinations and I am eternally grateful for his impact on my academic journey and my love for maths.
