Chemistry and Biology — both subjects, one expert. Learn from ex-MOE educator Mr Ken Chong in classes capped at 8 students. Dual-subject mastery. 80% of 2025 students achieved A1–B3.
"I joined IONX in Sec 3 doing combined science and with Mr Ken's guidance I managed to score A1 for both Chem and Bio in my O Levels. He explains hard topics in a way that actually sticks, not just for exams but for life."
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.
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.
Every Combined Science student gets full access to resources for both components — no extra cost.

"I joined IONX right after Prelims, scoring C5/6 for combined biology. In my most recent paper I scored an A1 with the help of IONX tuition. Thanks to Mr Ken, Biology has been enjoyable since then!"
"Mr Ken is very patient and dedicated to helping his students. He teaches in a very methodical way so it is easy to understand. Highly recommend for students who are struggling with their sciences."
"Mr Ken breaks down topics in a way that actually makes sense. I went from F9 to B3 in just 3 months. The notes and cheatsheets he gives are so much better than school materials."
"My child used to dread Chemistry. After just one term with Mr Ken, he's actually excited about it. The small class size really makes a difference — Mr Ken knows exactly where each student struggles."
