Course roadmap

Journey through our Secondary Mathematics course

Sec 3 & Sec 4 Mathematics

At Upper Secondary, students will deepen their proficiency in the subject and gear themselves up for the O Levels Mathematics examinations. Topics from Lower Secondary will be expanded upon and covered in greater depth, and new and more advanced topics such as Indices, Circular Measure, and Vectors will also be introduced.

Our Sec 3 and 4 Mathematics Programme will help students consolidate their learning, and achieve a sound mastery of all the key mathematics concepts acquired over the four years of their secondary school education. We will guide students to hone their examination techniques, and ensure they are well-drilled to effectively tackle common question types in the exams. Students will get access to examination-useful revision notes and trending O-Level questions. They will also practise mock examination papers under timed conditions. Our error analysis highlights common mistakes, and enables students to steer clear of these errors in the exams.   

Sec 3 & Sec 4 Additional Mathematics

Additional Mathematics presents a steep learning curve for students, as it involves more in-depth application of algebraic rules, requires more intermediate workings, and demands a rigorous understanding of core concepts.

Mind Stretcher’s Additional Mathematics programme uses a spiral approach to ensure that each topic is covered at appropriate levels in increasing depth. Students will be taught step-by-step methods to tackle questions, and learn how to present their answers clearly and concisely to maximize their marks.  Students will also experience differentiated learning through ample level-tiered questions in our worksheets. Instead of memorising the steps, students will learn to understand the logic and rationale, and acquire easy-to-understand steps to solve any Additional Maths problems.

Timely practices will be given so that students can master the skill of time-management. In order to let students effectively recognise the relationships between the topics learnt, they will be exposed to questions involving two or more topics.

Our testimonials

What our students & parents say about us

Mrs Shum is a very dedicated teacher. She has given me detailed feedback to improve my writing and her lessons are very engaging. I really appreciate the personalised feedback which helps me identify areas I should work on more. She goes the extra mile to share interesting facts every lesson which has helped expand my general knowledge in so many ways. With Mrs Shum's tips and MS Worksheets explaining how to master various components, I'm able to answer questions with greater confidence. Lastly, Mrs Shum cares deeply about our emotional well-being, and she always reminds us that trying our best is more important than the results.

I would like to thank the Chinese Language teacher very much for her effort, concern and encouragement for my child! He is very happy to be in her class and has enjoyed the Chinese Language lessons very much. He has tried his very best in the PSLE examination last year 2022 and his Chinese has improved. The constant encouragement from his Chinese Language teacher makes a difference and goes a long way!  Thank you Mr Kuek and all the teachers very much who has taught him and shared during the online bootcamp and the webinars! We really appreciate the effort, time, love and understanding put into preparation of the examination booklets and materials and staying behind after the online lessons to answer the students' questions! Wishing all the teachers and staff a very Happy blessed year 2023 ahead!

Dear Mrs Shum, thank you so much for all the guidance and support you’ve given me since i joined ms. Since i joined at a pretty late stage, i didn’t expect myself to acquire so much valuable knowledge that allowed me to learn English from a whole new perspective, as well as to perceive life in many different aspects. Thank you for always being so generous in sharing with us your personal experiences that engaged us during class, and making English such a fun subject for us explore the wonders of it! Thank you for taking the extra mile to further support me in English Literature as well, it really has been very useful!! It has truly been an eye-opening experience learning from you and I will remember these lessons as part of the unforgettable memories of learning in this subject❤️🥰

Mrs Shum is a caring teacher who is concerned about her students and their well-being. She has helped me improve in my English and has always been very caring towards me. She stresses on our mental health and has encouraged us a lot. Her teaching is amazing and i love how she shares interesting facts related to the topic we were studying and she exposed us to the basics of general paper too. To add, Mrs Shum gives specific feedback on our work which allowed us to know what we can improve on. The MS comprehension worksheets were also of great help as they allow me to know how to answer certain questions in a straightforward manner. Mrs Shum marks quite strictly which also further prepared me well for the O-levels where the marking is usually more lenient. As a result, I learnt how to do better and could gauge where i stand. Mrs Shum also made me realise that i was better in personal recount essays which allowed me to do well in the O-levels. Overall, MS worksheets were of great help and useful with specific tips and strategies. Thank you so much.

Dear Mr Alvin, Just want to text you to say "Thank you for all you have done for all the kids! Elvyn scored AL6 for his 2022 PSLE!“ A special mention to Teacher Meili, Teacher Audrey, Teacher Ryan and 丁老师。Not only were they never annoyed by his endless questions and constant requests for ways to improve himself, they guided him and encouraged him to do more and better. We are so blessed to have met all of you! I had introduced friends to send their kids to MS and will surely help to promote MS in the future too!

Mother of Elvyn Ee
I would like to thank Mrs Tan, who is my Mathematics teacher in Central Campus, for also teaching me tips and skills on how to solve well for Mathematics. She taught us a lot of tips on how to make logical sense on solving a question.

Glad Shannon has joined your group at sec 3 then... she has benefited tremendously under your charge. I still remember when Shannon failed math in Sec 2 term 3. But because she wanted to be eligible for A-Maths so badly she worked hard to pull up her results. Glad you had given her much encouragement to pursue her interest. She has benefited tremendously under your charge.

Parent of Wong En Xi Shannon
Teacher Shannel is very dedicated and enthusiastic to help my son regardless if it is mindstretcher or school’ maths problems that my son has, including Amaths which she is not teaching.. she response to maths questions on whatsapp quite quickly and enthusiastically.
