About Mike, the founder of Resident Sigma Maths

IB Maths AA HL is one of the toughest courses in the diploma — and generic tutoring rarely prepares students for the jump from textbook questions to examiner-level rigour.

Resident Sigma Maths is led by a qualified Mathematics teacher with 18 years’ experience across UK and international schools, a former Head of Department with one of the world's leading International Schools in China, and a current IB Maths AA HL examiner. Now based in Glasgow, Scotland, Mike has helped students from all over the world excel in HL Mathematics and brings a refreshing and friendly approach to classes that build on rigour, strengthens reasoning abilities and creates a learning environment where students are confidently able to upgrade their performance.

That dual perspective is your advantage. Students learn not only how to solve problems, but how to communicate solutions exactly as examiners reward.

Classes are taught personally in small mentor-style cohorts and built around examiner-designed materials, strategic thinking, and precise exam technique.

The results speak for themselves: year after year, the vast majority of students achieve 6s and 7s — far above the global average.

If you’re looking for a calm, expert-led pathway to top IB grades, Sigma is designed for you.
