Fall 2021 Schedule

We are offering 3 free sessions every week, starting on September 15. Email paulellis@paulellis.org for Zoom info.

All the sessions below are free and open to the public, but we do take donations!


1. Interactive recreational math presentation. 5:30-6:50 NYC time on Wednesdays.

Presented by Paul Ellis.

This presentation is open to people of all backgrounds. The content is chosen so that it is new to most people.

2. Introductory problem solving workshop. 6:00-6:50 NYC time on Thursdays.

Presented by Andrew Tu, Grace Lin, and Chinmayi Goyal

This is a relaxed problem solving workshop. To see if this is right for you, check out these two problem sets:

If this one is too hard to start, then you are not ready yet.

If this one is too easy, then this is not for you.

3. ARML Training. 3:00-4:30 NYC time on Saturdays.

Presented by Erik Brodsky, Matthew Zhao, and Jason Zhong

This class is designed for those who are comfortable with the AMC 10/12 and wish to train for more advanced contests. We will be using past ARML problems.
