**Note: Euler Circle will be held online until it is safe to resume in-person classes. ****You do not need to live in the San Francisco Bay Area to attend online classes. Over the summer, we will hold advanced classes on combinatorics and combinatorial game theory. In the fall, we will hold an intermediate class on transitioning to proofs in number theory, a class somewhere between intermediate and advanced on fundamentals of higher mathematics, and an advanced class on generating functions.**

Are you a high-school student in the San Francisco Bay Area who loves mathematics? Do you find the traditional mathematics curriculum far too easy? Do you want to learn fascinating and challenging mathematics? Do you want to work on problems and make friends with mathematically-minded peers? If so, you have come to the right place!

**What**

Euler Circle is a mathematics institute for advanced students in the San Francisco Bay Area who love mathematics. We offer a range of college-level mathematics classes, specifically tailored to the needs of advanced high-school students, many of whom have exhausted the mathematics curriculum at their schools and want to learn more. Each class we offer is the equivalent of a college mathematics class. In each class, students solve many problems to gain familiarity with new material, and in the advanced classes each student writes an expository paper on a topic related to the class material.

The classes are set up in such a way as to provide a pathway to independent research. Many of our problem sets in the advanced classes include unsolved problems that students can explore once they have mastered the material presented in class. We offer small group meetings for students interested in working on the research problems once they have demonstrated the ability to work hard on challenging problems. See more on research in Euler Circle.

**Why**

There is more to mathematics than competitions. Yet there are few resources available for high-school students to learn about the rest of the wonderful world of mathematics. We believe that many students would like to see what else is out there, and we want to share what we know.

**When/where**

Applications are open for summer classes, which will be online on Zoom. We will hold two advanced classes back-to-back. The first session will be on combinatorics, and the second session will be on combinatorial game theory. These classes will meet Monday, Tuesday, Thursday, and Friday mornings for 5 weeks each. Applications for the combinatorics class are due **April 25**, and applications for the combinatorial game theory class are due **May 30**. After that, we will continue to accept applications on a rolling basis while spots remain. Click here to apply!

Applications are also open for fall classes. It remains to be seen whether classes will meet online or in-person. Students not from the Bay Area are welcome to apply, but we cannot promise anything. We will have an intermediate class on transitioning to proofs in number theory, a class between intermediate and advanced level on fundamentals of higher mathematics, and an advanced class on generating functions. The intermediate class is tentatively scheduled to meet on Monday evenings from 5:30–8:30 PM Pacific time from September 20 — November 29 with a break on November 22, the fundamentals class is tentatively scheduled to meet on Tuesday evenings from 5:30–6:30 PM Pacific time and Friday afternoons from 4–6 PM Pacific time from September 21–December 3 with a break the week of November 23, and the advanced class is tentatively scheduled to meet on Tuesday and Wednesday evenings from 6:30–8:30 PM Pacific time from September 21–December 1 with a break on November 23–24. These dates and times are subject to change. Applications for these classes are due **July 25**. Click here to apply!
