How difficult would it be to transfer into Isenburg?

I have been accepted into UMass as an undecided major. When I submitted my application I accidentally chose school of Business as my second option. When I emailed an admissions counselor about switching he was not helpful and just said that it was a hard school to get into so I could not just switch, and didn’t give me any information about how I could switch if I chose to enroll at UMass. I was just wondering if I were to start out undecided, what I could do to transfer or what classes I could take, or if transferring to the Business School is possible.

This thread has some information on the subject:

Depending on what area of business you want to go into, you could also choose an Econ major as it gives you very similar options to business. Additionally, it is located in a separate school from Isenberg so it is much easier to transfer into. Good Luck
