One subject.
Two sciences. Full coverage.

Combined Science (Chem/Bio) under syllabus 5087 and 5088 requires students to master both sciences — but with tighter content, sharper application, and less room for gaps. Mr Ken teaches both, so the dots connect across subjects.

One tutor who knows
both sciences deeply.

Most centres split Chemistry and Biology across two different tutors. At IONX Labs, Mr Ken teaches both — so when Chemistry and Biology overlap (e.g. enzymes, organic molecules, respiration), the connections are made explicitly.

01
Homework Review
Track progress, surface recurring errors, and correct keyword mistakes from both Chemistry and Biology components.
02
Concept Deep-Dive
Difficult topics explained with diagrams, analogies, and cross-subject links that school teachers rarely make explicit.
03
Exam Technique Training
Chemistry needs calculation precision. Biology needs keyword precision. Both are trained explicitly every session.
04
Past Paper Practice
Real O-Level and Prelim questions with live marking scheme comparison — students see exactly where marks were lost.
05
Progress Review
Identify which component (Chem or Bio) needs more focus next session and set measurable goals.

One Tutor, Both Sciences
Mr Ken holds Honours in both Chemistry and Biological Chemistry from NTU. He teaches both components — so cross-subject links are made explicitly, every lesson.
👥
Max 8 Students Per Class
Hard cap. Every student gets individual attention — not lost in a 15 or 20-student group where weak areas are never addressed.
🏆
Grade Guarantee
We guarantee a minimum of B3 or improvement of 3 grades. Full refund if we don't deliver. That's how confident we are.

Common questions.

Combined Science covers two sciences in one subject — which means less depth per topic compared to Pure Chemistry or Pure Biology. However, because students juggle two components simultaneously, the challenge is managing both effectively. Students who score well in Combined Science understand how to allocate preparation time across both Chem and Bio, and know each component's exam format cold.
Yes — this is one of IONX Labs' key advantages. Mr Ken holds Honours in Chemistry and Biological Chemistry from NTU, meaning his degree specifically bridges both sciences. Most tuition centres use separate tutors for Chem and Bio. At IONX, one tutor teaches both, which means cross-subject connections are made explicitly during lessons — something separate tutors can't do.
We teach syllabus 5087 (Science — Chemistry, Biology) and 5088 (Science — Biology, Chemistry), both the standard Combined Science syllabuses for O Level students. All lessons are aligned to the latest SEAB syllabus and updated when MOE releases changes.
It depends on your schedule and needs. Some students attend a combined session where both components are covered together. Others prefer separate dedicated sessions for each component. We'll recommend the best arrangement based on your child's current performance in each component during the trial class.
We guarantee a minimum grade of B3 or an improvement of 3 grades in the O Level exam. If we don't deliver, we offer a full refund. This applies to students who attend consistently and complete assigned work. We include this guarantee because we're confident in our system — not as a marketing line.
The earlier the better — Sec 3 is ideal as it gives time for proper concept-building before O Level year. That said, students who join in Sec 4 or even after Prelims have still achieved significant grade jumps (ZY: Fail→A1, Jayden: C5→A1 after Prelims). There is no point where it's too late to see improvement.

Struggling in Combined Science
is now a choice.

Chemistry and Biology. One centre, one expert, one system that works. Join a trial class — no commitment, no pressure.
