The Online Math Club is an initiative to reach high school students interested in math and give them a platform to learn more and interact with others. The Club aims to increase exposure to olympiad mathematics and advanced mathematics. The format of the classes shows a great deal of diversity depending on the topic. Usually, they should be about 60-90 minutes in length and will be held over Zoom. You can join at sites.google.com/view/online-math-club/home.
