Your videos made me go from a 4 at the start of the year to a 7 in my first-semester exams. Thanks again.
Mr Flynn breaks maths down into a simple way to follow, gives great examples and explains each topic to the core. I can go back at any time to recap. I would highly recommend it. 10/10!
Coming from Spain and with English as my second language, it has always been hard to understand maths. With these videos, complex topics have been simple and easy to understand.
The videos simplify complicated maths topics. If I do not understand something in class, I am not panicked because I can open the videos and revise in my own time.
An amazing website that follows the IB course fully. The mathematical instruction is very clear and the pace supports independent learning.
