<p>I got accepted to Chemical Engineering, but since I've changed my mind about what I want to do with my life, and have decided that Mechanical is a better fit. Can I swich to Mechanical before class starts?</p>
<p>Yes, you can change majors, it's just a few clicks away on Minerva... provided, of course, that you do it before U3, hopefully before/around the beginning of U2, and that you consult/notify your advisor.</p>
