About Me

I teach because I remember what it felt like not to understand.

I spent years thinking I was just "bad at maths." Then a patient teacher changed everything for me. That moment is why I do this — because the gap between confusion and clarity is smaller than most students think, and the right explanation at the right time can change everything.

I hold a BSc. in Mathematics from the University of Colombo and have 8 years of experience tutoring students from Grade 6 through A/L. My sessions are calm, focused, and paced around you — not a syllabus timetable.

Outside the classroom, I'm an amateur photographer and an enthusiastic home cook. I believe both hobbies make me a better teacher — they remind me that mastery takes patience and repetition, and that the process is worth enjoying.

I failed my O/L Maths twice. After three months with Sarah, I passed with a B. She never made me feel stupid — she just kept finding different ways to explain things until one worked.

Sarah has a gift for making physics feel intuitive. My daughter was genuinely dreading A/L Physics — by the end of her first month she was looking forward to the sessions. The difference in her confidence was remarkable.

I came to Sarah for Python but ended up understanding computer science as a whole. She doesn't just teach you to write code — she teaches you to think. I now study Software Engineering at UCSC.

Computer Science · 2022

What I love most is that Sarah remembers every student as an individual. She keeps notes between sessions and always picks up exactly where we left off. It feels personal, not generic.

Isha Fernando

O/L Combined Maths · 2024

I'd given up on getting into university. Sarah helped me see that my problem wasn't ability — it was a few fundamental gaps that no one had ever filled properly. Three months later, I had an A for Maths.
