'O' Levels Chemistry & Physics Tutor

I am a NTU graduate with 7 years of private tutoring experience. I am proud to say that all of my students have gotten an A1/A2 for their 'O' levels science subjects!

I always work to ensure that my students understand the concepts and reinforce knowledge retention via consistent practice.

I also curate my own notes and have my own database of questions to help students gain more exposure of different question types.

My teaching methodology has produced an excellent track record of tutees scoring straight As for their science subjects and I do not intend to break that streak any time soon!


Group tuition - $40/hr

Private tuition - $80/hr

Feel free to reach out to me directly if you wish to work with me!
