Basics Review
This meeting on Wednesday is only listed on the exam schedule and is not listed in any other Summer School material that I could find.
Therefore I will treat the class as a recitation. We will not cover any new material, but will work on exercises and assignments.
*Courses in First Session on a 3-day-per-week schedule meet on Wednesday, May 21, in place of Monday, May 26.
*See link: https://summer.unc.edu/class-and-final-examination-schedules/
