O Level Science (Chemistry/ Biology)
Combined Science (Chemistry & Biology) equips students with essential scientific literacy across two core disciplines. The syllabus focuses on foundational chemical principles and biological processes, helping students understand how matter behaves, how living organisms function, and how both interact in real-world environments.
Students develop the ability to interpret data, explain scientific phenomena, and apply key concepts to daily life, from chemical reactions and energy changes, to human physiology and ecosystems. The course strengthens logical reasoning, observation skills, and exam techniques needed to succeed in the O-Level Combined Science papers.

Posted on - ATrustindex verifies that the original source of the review is Google. Teacher Ken has his own unique way of helping me memorise difficult concepts like QA and Organic Chemistry. High recommended!Posted on Shi Shiun CheahTrustindex verifies that the original source of the review is Google. Looking for a Chemistry Tutor last minute? Looking for Tutor to give you a fighting chance for Os? Ken Chong is the one and only tutor that can fulfill these criterias while also having reasonable and affordable rates. From the sad C5 Prelim score I got, he shot me up to an A1 in O Lvl Chem. He is above all in teaching memory shortcuts that help you breeze through the paper if you ever struggle with time constraints. He is the one you look for if you need difficult concepts nailed down. I STRONGLY RECOMMEND HIM IF YOU ON THE VERGE OF COLLAPSING AND CHEMISTRY DOESNT MAKE SENSE AT ALL. He is the last resort card to chem. I also do recommend him if you want a good start to doing Chem as well.Posted on Lawrence KohTrustindex verifies that the original source of the review is Google. Very good for chemistry and math!!Posted on cyensiTrustindex verifies that the original source of the review is Google. 很棒的老师!孩子情况比较特殊,他中四开始无心向学,学校的化学老师说他全年成绩在及格边缘,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!Posted on Joe XueliTrustindex verifies that the original source of the review is Google. Ken was tutoring my son during his O level from Aug to early Nov 2024. My son had an amazing experience with Ken. His teaching was engaging, clear and making the concept easy to understand. He is also very patient and always offer to consult him anytime to clarify any doubts via whatsapp or phone call. In the span of 3 months with Ken, my son grade 5 grades. I would highly recommend ken if anyone is looking for science tutor.Posted on Gracia NgTrustindex verifies that the original source of the review is Google. Very reasonable and affordable prices for secondary and JC tuition! Teacher Ken goes the extra mile to help students clarify their doubts! Highly recommended!Posted on Justin KoTrustindex verifies that the original source of the review is Google. Mr Chong is a tutor with great personality! Tuition centre is conducive as wellPosted on Li SinTrustindex verifies that the original source of the review is Google. Clean and conducive environment for learning.
