Best Science tuition I ever had, even though I joined halfway into my O lvl year, my Chemistry and Biology grades improved greatly over the short span of time. I'm thankful to have joined this tuition center, I recommend others to enroll for classes here!

Ken was tutoring my son during his O level from Aug to early Nov 2024. His teaching was engaging, clear and making the concepts easy to understand. He is also very patient and always offers to consult anytime via WhatsApp or phone call. In the span of 3 months with Ken, my son improves by 5 grades. I would highly recommend Ken if anyone is looking for a science tutor.

Attended tuition for Chemistry & Biology about 3 months before my N-Level papers. Managed to improve from a F9 for prelims to B3 for my N-Level results. Definitely recommend Mr Ken for your doubts in the subject!

Before joining Mr Ken's chemistry tuition, I had been struggling with grasping the concepts and formats of the subject. However, with his patience and guidance, he helped me understand these topics better and provided me with strategies to memorize and formulate my answers well. Thanks to his help, I was able to make a 5 grade jump (E8 → B3) from my prelims to O-levels.

My son began chemistry tuition with Mr. Ken, and we've been thoroughly impressed with the progress he's made. His grades have improved significantly — from a C5 to an A2. The small class size ensures that my son receives almost personal attention, and the worksheets and notes provided are well-prepared and highly effective for revision and practice. We're truly grateful for Mr. Ken's dedication and would highly recommend him.

很棒的老师!孩子情况比较特殊,Prelim C5 / O-level A1. 我是在考试前数星期找到Ken, 没想到改变了结局。儿子告诉我说,在非常有限的时间里,Ken老师要求他勤劳刷题,并耐心讲解他的错误与引导,同时也教他技巧如何熟记要点。再次,感谢老师!
(Great teacher! Prelim C5 → O-Level A1. Found Ken just weeks before exams — it changed everything. Thank you!)
