Understand and use Mathematical formulae easily to know exactly how to solve problems, from practising quizzes to answering actual IGCSE/SPM exam questions.
Step-by-step techniques for complete solutions from start to finish, with mastery of logical workflows required to answer questions confidently.
Improve exam scores by practising questions from reference book(s) and past-year IGCSE/SPM exam papers.
How to score high marks in exams while answering each question swiftly.
Build confidence via collaborative learning with peers and stay calm via motivation sessions before exams (upon request).
Application of maths and/or add maths in real life, since learning goes beyond textbooks, reference books, and past-year exam papers.
Clear frameworks to dissect complex problems without getting lost in the solution workflow.

Each student does at least one different question after each session to post the solution(s) into a WhatsApp group for discussion. It's better to learn together from mistakes early on than to make them during any exam.

Instead of merely understanding how to solve a problem or worse, memorising steps, the emphasis is on how to tackle it logically with mathematical thinking, a skill mastered by engineers, physicists, mathematicians and others.

You’ll be trained to think like someone working in Science, Technology, Engineering and Maths — how to logically approach and solve problems in reference books and past-year exam papers alike.

Live classes are recorded so that lessons can be watched anytime, and get help directly from Justin Lai through a personal WhatsApp group.

Questions from my own sources and past-year exam papers are distributed to each student and assessed online for everyone to view, but use your textbooks and other reference books to share solutions to problems for Justin Lai to assess.

Additional classes are organised not only to go through past-year exam papers together, but a mindset is also incorporated to stay calm, focused, and ready to score your best.
