Yesterday at Bama Bound I signed up for Calc III in the 12:00-12:50 time slot (CRN: 44566). Last night I was attempting to switch to the other Calc III course during the same time slot because I had heard that I would work better with that professor. However, after dropping the first Calc III course, the system is not letting me register for either Calc III class and says I do not have the required prerequisites. My AP scores (which UA has not received yet) will place me out of both Calc I and Calc II, and I had no trouble registering for this class earlier today. What can be done to get me back into my class? I emailed [email protected] about my issue, but I feel like that may not get the job done.
