mathleague.org organizes a series of classes each year to help students develop problem solving skills and prepare for math contests. Our flat price means NO materials fee and NO additional costs! We believe our prices and quality of instruction compare very favorably with other contest preparation options. Before signing up for any extracurricular math class, be sure to compare prices and instructors to make sure you are getting the best value for your money!

Online classes will be held in a third-party classroom environment with full two-way audio and video capability; enrolled students will be given detailed instructions regarding how to access the classroom system. All online classes are recorded so students who miss class or want to review the lesson can access the recording later. Please note that the recordings will be shared via Google Drive and class announcements will be sent over Google Groups, so in order to access the relevant information participants must share an email address that can access Google Drive and can be added to Google Groups.
