Class meets on Tuesdays and Thursdays from 1:30-3, but we’ll have homework due on MONDAYS and we’ll try to get it back to you on Thursdays.
Assignments will be posted here. You can turn them in on paper in the BP homework mailboxes or on Canvas as a single pdf.
Please budget 5 solid hours per week for outside-of-class work. Something like 1-1.5 hours to review your notes, 2-3 hours to work on problems (preferably in a group*) and at least 1 hour to write it up in your own words and concepts. Sometimes a single problem might take you over an hour. It’s worth it.
