Quick Question

<p>I was waitlisted to SOM and given the choice to Harpur. I decided to take the offer and major in economics and do a fast track mba through SOM. my question is that when do I state my major? When I submitted my application, I stated that my intended major was management. But now that I am going into Harpur, they don't know what I want to major in. What should I do? I had to write an e-mail saying that I would take the offer. Should I have stated the major in there? I am a noob when it comes to college stuff. Any feedback would be greatly appreciated. Thanks</p>
