Mr. Donny Cheh
Math & Physics Specialist (Sec/JC)
EDUCATIONAL QUALIFICATION:
- Bachelor of Mechanical Engineering (Honours) from NUS
TEACHING EXPERIENCE:
After graduating from the National University of Singapore, Teacher Donny began his career as an aerospace engineer before making the switch to full-time teaching. Since 2004, he has taught in tuition centres and served as a relief teacher in schools including Gan Eng Seng Secondary School, Woodlands Secondary School, and CHIJ Katong Convent. His experience in both school and tuition settings highlighted a common challenge: many students simply don’t receive enough individual attention in large classrooms.
This inspired Mulberry’s small-group approach, with classes intentionally capped at five students. Today, with over 20 years of teaching experience and more than 1,000 students taught, Mr Donny specialises in helping students identify learning gaps, strengthen their foundations, and build confidence in Mathematics and Physics.
Drawing on both his teaching experience and engineering background, he helps students understand not just what works, but why it works, turning confusion into clarity and confidence.

Mr. Riandy holds a Bachelor of Science (First Class Honours) in Chemistry & Biological Chemistry from NTU. During his undergraduate studies, he was awarded a full scholarship and was placed on the Dean’s List twice, recognising him as one of the top-performing students in his cohort.
Beyond his academic achievements, Mr. Riandy has accumulated over a decade of teaching experience, having guided more than 1,000 students from a wide range of schools. He is deeply familiar with the Singapore MOE Chemistry syllabus and has helped many students achieve significant improvements in their grades, including numerous top performers.
A firm believer that learning should be both effective and enjoyable, Mr. Riandy brings energy, humour, and real-world insights into his lessons. Students often describe him as patient, engaging, and exceptionally clear in explaining complex Chemistry concepts.
His passion for education began during university, where he volunteered as a tutor. Despite opportunities to pursue postgraduate research, he chose to follow his passion for teaching instead. Since then, he has dedicated himself to helping students build confidence, deepen their understanding, and reach their full academic potential.
