Eligibility
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.
Tuition
The tuition for the mathematical information and mathematical thinking classes is $850 per quarter. The tuition for other classes is $1100 per quarter.
Financial aid
We have need-based scholarships available. We highly encourage you to apply even if you are not able to afford the tuition, because there are funds available for financial aid. The amount of tuition reduction will be done on a case-by-case basis. Applications are evaluated on a need-blind basis, so you do not need to disclose your need for financial aid when applying; we’ll work that out later.
Application
To apply to Euler Circle, please fill out the form below corresponding to the class you are applying for. 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 2027 classes.
In winter 2027, we will have a mathematical information class, a mathematical thinking class, a transition to proofs class on transitioning to proofs in combinatorics, a class between the transition and advanced classes on fundamentals of higher mathematics 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.
