First of all I want to mention that based on my work experience these prices are much less than at any of the famous and not so famous learning centres. And quality is so much higher!

I offer small classes (no more than two-three students) and a sliding scale of rates.

Individual lesson (one to one) is $40/hr.

Group lesson (2 students): Grades 1 to 12 – $25/hr. It means you are Ok in general and do not have major problems but want to get 85-100% on your tests.

ALL SERVICES SUBJECT TO FULL HST

For more lessons per week you can -mail, call or visit and we will talk about it.

My lessons usually last one hour.
