Umass Amherst changing major

I was recently accepted to Umass Amherst and I was wondering how hard is it to switch major? I didn’t get my first choice which is Isenburg and I was wondering how / what the process is to switch?

From what I’ve heard, I believe you can reapply to Isenberg after your first semester. Just do well in your first semester courses.

You can transfer to Isenberg, but make sure that your first semester GPA is high enough. 3.6 or higher. The higher-the better.
