IP Mathematics at Orion is taught by Mr Anthony Lee and Ms Celia Chia — and together they bring a depth of IP-specific teaching experience that is genuinely unusual in Singapore’s tuition landscape.
Mr Anthony leads the programme and brings over 20 years of teaching experience across IP Mathematics, H2 Mathematics, and H2 Physics. His own academic journey — from the EM3 stream in primary school to the NUS Dean’s List — gives him a distinctive perspective on mathematical learning. He has worked with IP students from a range of schools over many years, including Raffles Institution, Hwa Chong Institution, Nanyang Girls’ High School, National Junior College, and others, and is well acquainted with the way different IP schools sequence and assess their Mathematics curriculum.
Ms Celia Chia is a dedicated full-time tutor who joined Orion since 2016 and has built a strong reputation among IP Maths students and parents for her exceptional patience in explaining complex concepts simply. Students who found certain IP Maths topics overwhelming — particularly in Functions, Trigonometry, and early Calculus — consistently describe how Ms Celia’s explanations made things click in a way nothing else had.
Both tutors share the same core teaching philosophy: never assume a student is ready for the current level of content on day one. Regular assessments are conducted throughout the programme, serving two purposes: to give students near-term goals that keep them motivated and on track, and to allow the tutor to structure revision more efficiently based on each student’s progress.
Our IP students come from CHIJ St Nicholas Girls’ School, Raffles Girls’ School, Raffles Institution, and other IP schools across Singapore.
