Science felt intimidating to me too — until someone finally explained it the right way, and everything clicked. I'm a neuroscientist, and before that, I sat the exact same IGCSEs your child is preparing for right now — Biology, Chemistry, Physics, Maths.

Tutoring Experience

For almost five years, I've been teaching science at this level, and here's what I've learned: most students don't struggle because they're not smart enough. They struggle because no one's ever broken the material down in a way that actually makes sense to them. I know exactly where the syllabus gets confusing, because I got confused there too.

Tutoring Approach

That's what I do. Every session is built around your child's specific gaps — not a generic lesson plan pulled off a shelf. My goal isn't just a better grade on the next test. It's a student who finally understands the subject well enough to explain it back to someone else. If your child needs support in Biology, Chemistry, or Physics at IB or IGCSE, I'd like to meet them.
