Join our expert tutor, Aline, as she provides you with Maths AA IB-Mock Revision Tuition. The revision course itself will be problem-based, as opposed to theory-based. So we will start solving a problem, and if there is any difficulty at any step, we will go back, revise the relevant theory, and come back to the problem. On both the first and second days, we will solve problems that would use a combination of several topics from below, instead of using just one topic. We will also pick up problems from old papers and other resources and solve them on the spot.

See our detailed Curriculum breakdown below.
