Class Marketing – On Sunday (5 April 2026), I received some good news from a former student whom I have probably coached for the longest period. She did well in her A Levels (name withheld for privacy). Briefly, I first taught her Olympiad Mathematics in person at her home when she was younger. She not only performed well in several Math contests, but eventually won the ASEAN Scholarship and went on to study in Singapore.
Later, we continued with paid online classes (I skipped teaching Statistics at A Levels onward, haha), and she continued to do well. Congratulations!
By Jonathan Ramachandran
She wrote: “Hi teacher Jon! Happy Easter 😀 hahaha thank you so much for helping me with math and I’ve gotten my A level results back and I did well 🙂 couldn’t hv done it without your help 🙏☺️”
I replied: “Hi XYZ, good to hear from you and Blessed Easter to you too! Good to hear you did well for your A Levels & all the best in your next course of life! 😇😎”
For one-to-one Zoom Math class enquiries (preferred), please contact me at +60108803763 (WhatsApp message preferred). Thank you.

Respected Parent: “Good evening Mr. Jonathan, I have good news and I want to share with you. Thanks for your teaching and so AA can get Gold award in APMOPS. … If so, hopefully Mr Jonathan can help AA prepare for it. Again, thank you very much and I really appreciate your teaching.”
Myself: Hi Mr. AAA, oh sorry I am in class. This is great news! Congratulations to AA as he is a bright student! 🙂 APMOPS is very respected private Olympiad and I am very glad he achieved a Gold in it 😀. Definitely, will be my pleasure to continue teaching him what I know to help him prepare further in this competition and beyond. Thank you so much 😎
[Text]: Compare this: there are many Chinese vernacular schools in the country, along with numerous respectable private Math and other Olympiads for their students, without waiting for government funding or relying solely on government-based contests (which also exist separately).
In comparison, among Tamil vernacular schools in the country, I have not heard of even one Math Olympiad contest. Can the community and funding organizations not afford to organize one? I have proposed this in the past with others, but none of their “education foundations” have shown interest so far, or they claim there is “no money” for it.
I believe this is a betrayal of the students—one must pity them—by a community that lacks educational initiatives of this kind within itself. I am ready to contribute to its formation, not out of prejudice nor as a racist, but because I also belong to this marginalized community and have seen that there are no proper, high-quality Math Olympiad contests available for them by themselves, independently either.
