This course has two recitations each week. These recitation sessions emphasize concepts from the lectures and focus on solving problems in small groups. In-class participation during the recitation sessions counts for 20% of a student's grade. The grade is based mainly on the degree of active, prepared participation in the small group, rather than problem-solving success.
