Are you struggling with Primary or Secondary School Mathematics?
Our MOE-registered Math Tuition Centre is dedicated to helping Singapore students excel in their Primary PSLE and Secondary O Level Mathematics exams!




Lack of Personalised Support
In large classrooms, students often miss out on individual attention, making it difficult to fully grasp key concepts. Our small-group lessons ensure every student receives the personalised guidance they need to build confidence and mastery.

Limited Exposure to Exam-Ready Questions
Many students struggle with challenging exam questions that go beyond basic concepts. We provide a variety of problem-solving techniques and exposure to diverse question types, helping students tackle any challenge with ease.

Difficulty with Advanced Math Concepts
As students progress to upper primary and secondary levels, complex topics like algebra and trigonometry can be overwhelming. Our structured lessons reinforce foundational skills while preparing students for advanced topics, ensuring they stay on track and don’t fall behind.

Testimonials
Parent of Wynn Ern, Raffles Girls School
I would like to thank Ms Chang for her exceptional teaching and dedication. My daughter speaks highly of Ms Chang and blessed to be taught by her. Ms Chang explains complex concept clearly, patiently clears doubts, provides constructive feedback and invaluable advice. Her efforts, patience and commitment have made a significant difference in my daughter’s understanding and learning progress, especially the improvement in her recent exams, has been remarkable. Many thanks to the admin team too for the great support and prompt assistance, always. I would highly recommend Ms Chang & Sirius Mathematics.
Parent of Evelyn Yow, CHIJ St. Theresa’s Convent
I decided to give this new tuition a try and it is amazing! My child attended teacher Jian Xuan’s Sec 1 math class in term 2. She managed to jump from E8 in term 1 to A1 grade in WA in term 2. Amazing progress there and thanks to teacher Jian Xuan for helping my child with the foundations and techniques! Love the new modern space as well!
Parent of Clarine Teo, Geylang Methodist School (Secondary)
My girl attended a Sec 2 math crash course through word of mouth. She was able to understand the concepts well. Teacher Ms Chang was very clear in her explanation.
Parent of Kady Chan, Raffles Girls School
Very pleased with Sirius Math, especially Ms Chang. After 1 term, my girl Math results improved from 20/30 to 29/30. The premises are new, and the free flow of tidbits add the icing to the cake, always making my girl looking forward to the lessons!
Parent of Jeremy Yap, Queensway Secondary School
My son joined the March holiday crash course and found the explanations in the class very good. The teachers were very patient. Despite being a group class, the teachers still managed to provide undivided attention to my child. It was a great recap of the Term 1 topics. My son also enjoyed the free pizza.
