See what the students that took chemistry and biology tuition with us in Singapore say about their O-Level results.
"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."
"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!"
"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."
"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."

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 what you need, not the average of the class.
Acronyms and answer templates built from 10+ years of marking O-Level scripts, plus cheatsheets for every topic. Students walk into the exam knowing exactly how marks are awarded.
We cover content before school does, so students get time for mastery instead of cramming. Pre-recorded lessons, TYS solutions, and prelim papers from day one.
Students here call themselves "Biochemists." There's food every session and a culture where showing up and doing the work is just what everyone does.
"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."
