Announcements
If you scored lower than 5 on the second exam, you are at risk of failing the class. Students in this situation must complete a “redemption” assignment, which is due on April 4. This assignment simply requires you answer Question 4 (all parts) and Question 6b from Problem Set 2. Satisfactory work on these questions will keep you on pace to pass. You may work by yourself or in groups to understand how to solve the questions, but the ultimate write up must be your own. Note that completion of this assignment does not guarantee a passing grade overall in the class, as an unacceptable grade on the third exam could still result in this unfortunate outcome.

We will not be meeting during the university-scheduled final exam period. Instead, the final exam will be administered on April 20 during the normally scheduled class period.
