Class Description:

This study group class is for students who have a working knowledge of the USACO Bronze level algorithms, and have taken [USACO BRONZE] (or equivalent). Students do additional practice and discussion on more advanced problems within the level in a guided group environment. This study group spends more time on practice and discussion than lectures and introductions. This kind of open-ended work helps students get past sticking points in problems and clarify lingering questions about underlying concepts. Students may guide some of the discussion by bringing up problems or topics they'd like to focus on. The regular meetings of the classroom format also help students ensure they're sticking to a healthy practice schedule.

Background: The USA Computing Olympiad (USACO) requires a significant amount of time reviewing and practicing in order to promote to the next level. This is true even after initially learning problem-solving strategies in a class or through online study materials. Group study like this can be a big contributor to putting in that necessarily follow-up time and increasing the chances for promotion!
