Chemistry & Biology Tuition Singapore
— From Failing to A-Grade.
Singapore's most results-driven chemistry and biology tuition — by ex-MOE educator Mr Ken Chong. Classes capped at 8 students. Structured exam frameworks. 80% of 2025 students achieved A1–B3. See results →
"My pure chem went from D7 to A2 at O-Levels. Ken goes out of his way for every student — if not for him, I would never have given chemistry a second chance."
5.0 rating — "Literally the best out there. I went from failing to A2 in combined science after joining just after prelims."
Real students. Real grades.
Not cherry-picked outliers. Every student below joined our chemistry and biology tuition in Singapore and sat for their O-Levels.
"My mother signed my sister and I quite late into Sec 4. BTW I obtained A1 for my sciences!! His teaching was easy to understand — memorise the important details with his acronyms. He also explains any queries and offers consultations after tuition!"
"My pure chem went from D7 to A2 at O-Levels. Ken is extremely willing to go the extra mile for students — he goes out of his way to ensure queries are answered and takes care of his students' mental health. If not for him, I would never have given chem a second chance."
"Ken shot me up to an A1 in O-Level Chem from a C5 Prelim. He is above all in teaching memory shortcuts that help you breeze through the paper. I STRONGLY RECOMMEND HIM IF YOU ARE ON THE VERGE OF COLLAPSING AND CHEMISTRY DOESN'T MAKE SENSE."
"Ken shot me up to an A1 in O-Level Chem from a C5 Prelim. He is the one you look for if you need difficult concepts nailed down. I STRONGLY RECOMMEND HIM."
"My son went from a very poor fail to three grades higher in Chemistry O-Level preparation — in under six weeks. Ken is truly dedicated and gives his 200 percent."
"We found IONX Labs five months before O-Levels. My daughters were borderline passing or sometimes failing. With structured guidance, they achieved A1 and B3. Highly recommended."
"Attended tuition for Chemistry & Biology about 3 months before my N-Level papers. Managed to improve from F9 for prelims to B3 for N-Levels. Definitely recommend Mr Ken!"
"Ken is the best teacher in the world!!! Helped me get an A2 for Os from a fail and encouraged me not to give up when I got bad grades. Very caring towards all his students."
"She had been failing and never liked Chem. After 4 months — switching from Pure to Combined mid-year — she got A2 at O-Levels. I am grateful for Teacher Ken's patience and care."
"Teacher Ken pulled my Chemistry grade from a D7 to an A2. He is a very patient and creative teacher — creates ways to help me understand the subject. The best teacher I have ever met!"
"With his patience and guidance, I was able to make a 5 grade jump improvement from my prelims to O-Levels. He helped me understand topics and gave me strategies to formulate answers well."
"I join 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!"
"My son improved significantly — from C5 to A2 — which reflects the quality of teaching and support provided. The small class size ensures almost personal attention. Highly recommended."
"Ken shot me up to an A1 in O-Level Chem from a C5 Prelim. I STRONGLY RECOMMEND HIM."
"My son went from a very poor fail to three grades higher in Chemistry O-Level preparation — in under six weeks. Truly dedicated."
"With his patience and guidance, I was able to make a 5 grade jump improvement from my prelims to O-Levels."
"I joined AFTER prelims till O-Levels. The tutors are extremely patient and explain concepts in a way that actually makes sense. I managed to get A2 for science."
Not all Chemistry and Biology Tuition
in Singapore is equal.
Hard cap of 8 students. Mr Ken knows your weak points, tracks your progress, and adjusts every session to your specific needs — not the average of the class.
Proprietary acronyms, structured answer templates, and high-yield cheatsheets built from 10+ years of O-Level teaching. Students know exactly how to score on exam day.
We cover content before school does, giving students time for mastery rather than cramming. Pre-recorded lessons, TYS solutions, and prelim papers from day one.
Students identify as "Biochemists." Food every session, a modern environment, and a culture that makes students actually want to show up and put in the work.
"Every student who walks in with a failing grade leaves knowing they can do this. The frameworks work — but believing in the student comes first."
The I-O-N-X Framework.
