Can I change my major now for Penn State?

<p>So, I just found out that I got accepted into to The College of Liberal Arts at Penn State-University Park, which I'm pretty happy about but uh, I did the application months ago and chose my major as History but I've been researching the last couple months and I've realized that I want to major in Biology instead.
So, can I still major in biology, can I change to the College of Sciences or something at Penn State?<br>
How does this work? Am I locked into liberal arts?
Would appreciate some responses, thanks.</p>
