Tell us where you are, where you want to get to and how much time you have. We will
show you the problems between the two, and what it takes each week to get through
them. Move anything and the numbers follow.
Time per problem is estimated from the stage: ten minutes at stage 3, two hours at
stage 9. It is an estimate, not a promise. Some problems will fall in minutes, others
will ruin your evening; that is olympiad maths. What you choose is saved in this
browser, and to your account if you have one.
