would getting a W make you look bad after you've been accepted? I was enrolled in microecon (a pre-req) for spring, but decided to drop it so that I could take it in the summer. Could the school not accept me anymore?
Yes, definitely check with the school because most if not all want you to finish ALL of your pre-req by the end of the spring semester/quarter. A lot of the schools that i saw won't accept any summer classes before pharmacy school for that year. So you need to call the school and ask.
