# Is there a required textbook?

We develop and maintain our own lecture notes and problem sets (with many problems from past competitions), and do not use a third-party textbook for any of our courses. By enrolling in a math course (MC15 through MC50), students will have access to all materials for that course online.

For in-person courses, students will be provided a hard copy of the textbook for their course. Students enrolled in online courses can email <info@alphastar.academy> to inquire about options for purchasing the textbook.
