STEM-FOCUSED LEARNING STUDIO

where curiosity meets community

Our Classes

Sigma Collective offers a wide range of classes for students all the way from Primary to Secondary and Junior College level.

Primary School Science

Let curiosity bloom. Our Primary School Science programme turns wide-eyed questions into confident understanding, guiding students through hands-on concepts, clear explanations, and exam-ready skills that grow with them.

Lower Secondary Science

Strengthen fundamentals and prepare for upper secondary. Our Lower Sec Science classes break down complex ideas into simple, relatable examples while developing strong answering skills. Students gain confidence across Physics, Chemistry, and Biology.

Upper Secondary Biology

Bring Biology to life with engaging visuals, clear content breakdowns, and targeted worksheets. We help students understand processes—not memorise blindly—so they can confidently score in structured and application-based questions.

Upper Secondary Physics

Turn Physics from confusing to crystal clear. Our Physics programme focuses on conceptual understanding, real-world applications, and consistent practice. Students learn proven methods to tackle calculation-heavy questions and ace O-Level Physics.

Upper Secondary Chemistry

Master Chemistry with a step-by-step approach. From chemical equations to organic chemistry, our lessons simplify challenging topics and build strong problem-solving skills. Perfect for students who need clarity, confidence, and exam mastery.

JC H1/H2 Mathematics

Our JC Math programme emphasises deep understanding, speed, and accuracy. Students learn structured methods, exam strategies, and the ability to tackle challenging application questions with confidence.

What Our Students Say

U to B3 at O Levels

Before starting my tuition with Mr Huz, my grades for combined science were at an all time low. However, after just a few lessons it was evident that not only had my grades improved, but I even started to enjoy the subject! Mr Huz’s lessons were fun and informative, every session I took home new skills and concepts. From a failing grade of U, I managed to score a B3 for O levels. His attentiveness towards my weaker topics truly guided me in the right direction, his explanations being precise and easy to understand, often using real life examples and even random things in the room.

F9 to A2 at O Levels

Before joining lessons with Mr Kenneth, I had been doing poorly in combined biology in weighted assessments and other tests. After joining his lessons for a couple of months, I felt more confident about the various topics tested and ultimately achieved an A2 for the subject (chem and bio combined). Mr Kenneth is an efficient teacher and knows how to explain various and sometimes confusing topics in an understandable way.

S to A at A Levels

After discovering Ms. Shalyn’s A Level Functions video on YouTube I had high hopes about her ability to make complex topics into something more manageable. I actively sought her out, that is a great decision on my part as I find her explanations easy to digest, and her breakdown of each question intuitive to understand. I highly recommend anyone who wants to do well in H2 Maths to seek her out like I did!
