Tutor Information


Hello! Welcome to TutorOcean. My name is Kelvin and I am here to help you. I hold a BSc (Hons.) in Physics and an MSc in Applied Mathematics. I have been teaching math for over 14 years now. I have a proven track record of success spanning over a decade of teaching and private tutoring mathematics in high-achieving schools and colleges in the United States, Canada, and the United Kingdom. I can help improve your calculus, pre-calculus, algebra, pre-algebra, geometry, trigonometry, and differential calculus skills in no time. I can also give premium support for test and exam preps (PSAT, SAT, IGCSE, ACT, GED, AP, IB, GRE, and many other school and college entrance exam preps). Because everyone learns at a different pace, I will tailor our one-on-one sessions to your specific needs. During the first session, I will assess your abilities as well as the skills you wish to improve. Then design a comprehensive plan to meet your goal. I highly encourage you to book your first session with me to see how math can be both enjoyable and understandable. Thanks, and see you soon.

Exceptional Tutor

My daughter has been taking math lessons from Kelvin for the past few months. Since then, her grades have improved significantly. He has just started teaching my son too. Kelvin's style of tutoring helps my kids understand math concepts so easily. He also uses an online collaboration tool that my kids find very useful. We are very happy that we have found a good math tutor in Kelvin for our kids.

We couldn't be happier with Kelvin. If I could, I would give him 6 stars! He has great knowledge of a wide range of math topics. Most importantly, he makes math fun. Our son says his positive energy is infectious; he now looks forward to his classes... even during the summer holidays. He's done a fantastic job getting our son ready for the 9th grade, and he is doing excellently well in school right now. Thanks to Kelvin!

Outstanding Tutor

I am an adult learner who has been learning with Kelvin for many months. We have been studying prealgebra and algebra together. He is incredibly patient, encouraging, and an excellent tutor. I really cannot recommend him highly enough. He is the teacher I wish I had when I was in school. He is also punctual, organized, and dedicated to his teaching.
