IB Mathematics, taught one student at a time.

I’m Alex Koo. I have taught mathematics to international-school students in Singapore for more than 16 years. I will take on a small number of new students for home-visit 1:1 tutoring from May 2027, and university admissions consulting is available now.

Places are limited and offered after an interview and placement test.

I review how the student studies as a whole, including habits, planning and revision, and teach methods that make study time more efficient in every subject.
