Any Post Bac out there?

<p>I'm currently a senior in UW and going to graduate in June. However, I just feel like I picked a wrong major and I'm frustrated and hoping apply to UW again in the future for a completely different field. I don't have a really competitive GPA, around 3.2. I just wonder if anyone here has been accepted as post bac student in UW before and able to give me some advice.</p>
