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 course costs $900. 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 will waive the fee.


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 our Fall 2019 classes. In Fall 2019, we will offer an advanced class on cryptography, and also an intermediate class on transitioning to proofs in number theory. Although the application deadline has passed, it may still be possible to accept a few more students on a first-come first-serve basis. It is not worth spending a huge amount of time worrying about this application; fill it out quickly and then go back to learning mathematics. We will send you a confirmation email shortly (within 24 hours) after you apply; if you do not receive one, then that means your application was not submitted successfully.
