Engineering @ UCSD

<p>Ok. So I was admitted as a General Biology major at Sixth. However, I really want to do engineering. (Bioengineering/Mechanical) I know that these majors are both impacted so I can't just switch. But I just want to know. How difficult is it to switch into one of them? After taking the Pre-Req's, can I apply to switch into both? Or only one?</p>

<p>Thanking you in advance for your responses.</p>
