How it works

All sessions are free and will be conducted either remotely via Zoom or in-person in groups of about 5-10 students. Each class will meet for two 45-60 minute sessions every week. We emphasize creativity, problem-solving, and collaboration in order to foster a welcoming environment where students can form lasting friendships.
