HONG KONG, March 18, 2026 — WSMATH Limited today announced the ongoing expansion of its high-end online mathematics tutoring, fueled by Founder Winson Siu’s move from in-person tutoring to an exclusively digital, premium teaching service. The platform, now a multi-million HKD enterprise with consistent annual growth, meets the increasing worldwide need for specialized help in the International Baccalaureate Diploma Programme (IBDP), General Certificate of Education Advanced Level (GCE A-Level), International A-Level (IAL), and International General Certificate of Secondary Education (IGCSE).
Founder Winson Siu started his mathematics teaching career offline in 2017, prior to making a complete transition to online lessons in 2021. His approach employs digital tools to facilitate live, interactive problem-solving. Throughout the last eight years, Winson has accumulated over 18,000 hours of teaching through 11,000 individual sessions for more than 250 students from top international and local schools.
The company sets itself apart by delivering significant academic improvements for students from various initial ability levels. Prominent achievements feature an IBDP Standard Level student who raised their grade from a Level 3 to a Level 7 in just 1.5 months, and two IBDP Higher Level students who progressed from Level 3 to Level 6 in about three months. Winson also guided a self-studying IAL candidate, who initially had a weak grasp of mathematics, to earn an A* grade in both IAL Mathematics and IAL Further Mathematics. As Winson’s first IAL student, this individual later gained admission to the University of Cambridge, showcasing a teaching talent developed through clear explanations and a methodical system, rather than formal teaching qualifications.
Winson’s educational approach is deeply shaped by his experience within Hong Kong’s exam-focused schooling system. He achieved an A grade in the Hong Kong Advanced Level Examination (HKALE) Pure Mathematics, a result attained by only the top 4.8 percent of examinees in Hong Kong. “Being educated in a high-pressure testing environment taught me to deconstruct problems methodically and to pinpoint the precise factors that differentiate an exceptional performance from a mediocre one,” Winson stated. “My instruction closes this divide by integrating these stringent methods with the demands of international syllabuses. This provides students with a disciplined, examination-oriented mindset that is frequently lacking in conventional classroom settings.”
The firm underscores a clear shift away from passive educational approaches. In contrast to traditional classes where instructors might use slides or videos and assume students will learn on their own, Winson offers fully engaging, live teaching based on real-time handwritten notes, dynamic questioning, and instant feedback. This comprehensive knowledge of international exam standards comes from reviewing more than one hundred past papers for each subject syllabus. Student testimonials affirm the effectiveness of this method. One pupil commented that Winson “breaks down complicated ideas into straightforward, logical steps,” and another reported moving from being at the lower end of the class to scoring among the highest, crediting the “topic-specific past paper system for revolutionizing my approach to learning math.”
Winson’s dedication to his students is further demonstrated by his demanding schedule during important examination windows. In 2018, he held a nine-hour marathon session from 18:00 to 03:00 to assist an IBDP student. Later, in 2025, he undertook a non-stop 19.5-hour teaching day from 06:00 to 01:30, highlighting a rigorous commitment to his students’ achievements.
