I just had an interview at UPENN, and the dean of admission director said that if I plan to change my planned coursework for the spring semester, I have to let them know as via email as soon as possible or else they will rescind my acceptance. He seemed very serious about this and said that this goes for all schools. Is this true?
For context, I plan to take a 4-credit physiology course instead of a 5-credit physiology course (which I indicated on my aadsas) application because I will have more free time in my spring semester.
