Students are required to sign up for recitation at available times. The recitation classes will meet either in Thaw 11 or, on most alternate weeks, the Physics/Astronomy/Chemistry Computer classroom in the Chevron building (announcements will be made). Attendance will be taken at recitation classes. The recitation classes provide time for: discussion of homework problems assigned during the lecture class, asking/answering questions on lecture class topics, more detailed consideration of any in-class demonstrations , and doing work in the computer classroom which will help the student gain some practical experience on lecture class topics. The times for recitation are listed below.
