We believe that every student have a true potential within them, no matter the type of academic results they showcase. We at Onetone want to bring out that potential from our students and pass on the philosophy that studying is not just about academic results, but also about what they haven’t learnt and how they can apply these lessons in real life context. We also want to hear what the children have to say regarding their own academics, school and studies. With over 20 years of experiences in teaching, our team of top scholars specialise in many types of subjects and are truly passionate about teaching and making lessons enjoyable and educational. We deliver results and goals, work hard together with our students. Working towards the goal isn’t the end and the results but the journey and the lessons you have learned along the way that is just as important.

Throughout the years, we have touched the lives of many students. Here are some of what our past students have to say.
I wanted to get into ACJC and to do that I needed to get an A1 in my Maths and Triple Sciences. I was only scoring A2s and B3s thus, enrolled into Onetone when I started Sec 4. Slowly, but surely, I started improving and getting the results I wanted working along with my tutors. With hard work and smart studying techniques, I scored a Distinction for my Maths and Sciences. I’d like to thank my teachers for helping me achieve my true potential And the team of staff at Onetone who gave me flexible schedules despite my busy school schedule.

I was failing my A-math and barely passing my E-math. After being enrolled into Onetone 6 months before my ‘O’ Levels, I saw first hand how my results changed and how I was capable of achieving As and Bs in my maths. My teacher, Mr Poh was very fun and passionate about teaching us. His assessment papers were challenging but manageable as he went through each concept we were unsure of. For my ‘O’ Levels, I scored a Distinction for my E-math and A2 for my A-math. Thank you Mr Poh, for believing in me and helping me.

I have been studying at Onetone for 5 years since Primary 5 and I have become close with the staff and the teachers here. I have always been a slow student who could not grasp concepts taught at school well. After joining Onetone in preparation for my PSLE, my grades slowly started climbing up and eventually got into Express stream and now done with ‘O’ Levels. Onetone have been part of both of the most important exams in my life and both of which they have greatly helped and I scored L1R2B2 of 10 points for ‘O’ Levels. Thank you, Mr Ken, Ms Kek, Mr Oerry and many other teachers who have helped me during my time at Onetone for the past 5 years!
