Note: Euler Circle will be held online in the winter quarter, and possibly after that as well depending on the COVID-19 situation. You do not need to live in the San Francisco Bay Area to attend online classes.


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. Note that our classes are in-person classes in the San Francisco Bay Area unless otherwise noted; do not apply if you do not live in the San Francisco Bay Area!


Each normal-length course costs $900. The complex analysis class, which is twice as long, costs $1800. 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 2021 classes. We have an intermediate class on transitioning to proofs in combinatorics and an advanced class on complex analysis (which is a 2-quarter class covering the winter and spring quarters). These classes will also be online on Zoom. You do not need to live in the San Francisco Bay Area to attend online classes; students from around the world are welcome. Although the application deadline has passed, it may still be possible to accept a few more students on a first-come first-server basis.
