Under normal circumstances, students should not have completed high school by the beginning of the course. There is no official lower age limit, but we expect students to have the mathematical maturity of advanced high-school students.


Each normal-length course costs $1000. However, if you are unable to pay, or if it would cause financial hardship, let us know (once you have been accepted only), and we may be able to arrange for some financial aid.


To apply to Euler Circle, please fill out the form below. As part of your application, please enter the name and email address of a math teacher we may contact in case we have any questions.  This can be a teacher from school, or from a math camp or other extracurricular program. We will not necessarily contact your teacher.

We are now accepting applications for the Winter 2023 classes. We have an intermediate class on transitioning to proofs in combinatorics, a class on fundamentals of higher mathematics at a level between intermediate and advanced focusing on real analysis, and an advanced class on gems of linear algebra. It will be possible to take these classes online or in person. You do not need to live in the San Francisco Bay Area to attend online classes; students from around the world are welcome. Here are the dates and times for the three classes:

Class Starting date Ending date Everyone Online In person
Transition to proofs January 9 March 15 Monday 5:00–6:00 PM Tuesday 5:00–7:00 PM Wednesday 6:30–8:30 PM
Fundamentals of higher mathematics  January 9 March 15 Monday 5:00–6:30 PM Wednesday 5:00–7:00 PM Wednesday 6:30–8:30 PM
Gems of linear algebra  January 9 March 15 Monday 6:30–8:30 PM Tuesday 5:00–7:00 PM Wednesday 6:30–8:30 PM

Applications for the winter classes are due November 20th. After that, we will continue to accept applications on a rolling basis while spots remain.
