I noticed that students have been struggling with similar concepts on Sections 1 and 2, so I just added around 15 additional drill problems within the supplemental materials section of the course. Most questions are about the Counterparty Credit Risk reading, which seems to be one of the trickier ones for students. Hopefully this extra practice will make you feel more comfortable with the concepts in those readings!
There were no changes to the existing drill problems and all new problems have been added at the end of each section.
