Hi! I’m an admitted ED applicant from the Class of 2021! I am very excited I get to attend Wash U 
I am currently enrolled in the CAS and was wondering how easy it would be to transfer into Olin School of Business. More specifically, would I be able to transfer before I start classes next fall? Thanks!
I think that this would be a good question to just call admissions up and see what they say. I’m sure there are others just like you wondering the same thing. Although I had heard that transferring between colleges is easy, I’ve also heard that Olin was really competitive this year and had like a 10.3% undergrad acceptance rate with a incoming freshman class size of about 160. I would say just give admissions a call.
I just called admissions. They explained transferring is very easy between the colleges, however, Freshman must wait until they complete one semester in the school they applied into before they can transfer. Pretty sure it’s as simple as signing a piece of paper.
