Hi,
I have a questions about majors. If you fill out major X as your intended major on the common app, are you bound to that major if you decide to change to major Y once you attend? In what ways would it be different if you had already listed major Y rather than X as your intended major on the common app? I thought you don’t declare your major until sophomore or junior year. Also, I’ve heard people say it’s hard to transfer majors, what do they mean by that? What if the major is in the same college (say the engineering college)?
Thank you guys so much for your help!
