Changing major after transferring to UCR

<p>Hi Guys, </p>

<p>So I applied to UCs this season and a i got into UCR but for my alternative major of Global Studies which wont get me anywhere in life. I originally applied as Bio but since that is a bit impacted i was thinking of changing my major to Environmental Science or Psych when i got there rather than facing a rejection from bio again. My main goal is eventually get to med school so i just need the prereqs for that done, but i still want a degree of substance that i can survive off of if med school doesnt work out.
I'm a transfer student so i'll be entering as a junior and i really dont want to delay graduation too much and i def dont want to be at a CC for another year. Has anyone does this before at any UC but more specifically UCR? Any suggestions/advice? all is appreciated. Thanks!</p>

<p>GPA:3.34
