Hello , My name is
Joseph Khan
I am the founder of GREAT Academy for student centric education. Also, I’m an IB examiner for IA and Paper 3 in AA HL Math. For 20 years I’ve been teaching HL Math to high school students from all over the world. But this part of my journey didn’t start in the classroom. It began on Wall Street, where I ran my own IT business for two decades. I’ve seen firsthand what separates those who just get by from those who excel, and it’s not only talent or effort. It’s a strategy.
Testimonials
Anais
Student
Throughout my final years in high school Mr Khans perseverance, patience and wisdom took me from a D in maths to an A-.
I’ve never met a teacher more present and dedicated to the success of his students and willing to go deeper to understand what is holding someone back from reaching their full potential. Mr Khan was always, and I mean always, available to go over a problem, a concept or an assignment which was invaluable in helping me build my confidence and skills. He’s the best maths teacher anyone could ever hope for and he’s funny too, which makes the whole experience of high school maths a bit more enjoyable!

Dear Joe,
I received IB results and wanted to let you know how your student did.
He got a five. Thank you so much! I’m super happy for him that he brought his math score from 2 to 5. Well done.
As always, you perform amazingly. And I wanted to thank you personally. It’s a huge deal for this student to get a five for the IB exam when before he was failing math completely. Thank you!

Thank you so much for helping me learn and adapt to the rigor of the class. You have helped me learn how to deal with a “hard” course.

Dear Mr Khan, You have helped me grow as a mathematics student so much. At the beginning of the year I was struggling. Now math is one of the classes that I enjoy the most. Thank you for everything!
