Registration is taking place now for University of Chicago Cascade.  The winter program takes place on Tuesdays from January 28 - February 25.  Cascade is a program for high school students that exposes them to interesting topics they may never have seen before high school.  It allows students to meet other high school students in a fun context and allows them to explore topics in depth.  There are no tests or grades, but there may be small amounts of homework assigned from week to week in some classes.  Attendance at all sessions is required.
