Chem 51/51LB

  • Due to a programing issue in the Schedule of Classes, students that were trying to enroll in Chem 51B/51LB or were waitlisted for one of these classes were dropped from their Chemistry classes on 12/20/18. If you were affected by this issue please email and the Department will respond in early January to assist you in enrolling. Students that have O-Chem required for their major will be given priority.

Chem 107L

If you have a conflict in your schedule, please email (after you have enrolled in all of your other courses) to request manual authorization into Chem 107L.
