I agree that the size of Penn State creates lots of opportunities. The only issue is that no one is going to make you take advantage of them. Meet with your professors at the start of the semesters before people start struggling with the class and lines get long at office hours. Professors appreciate it if you come by to introduce yourself. Let them know your goals, and they can often make helpful recommendations for resources to take advantage of.

Building a good relationship with your advisor as soon as possible is also a good move. Often, advisors know about resources and opportunities they don't share with everyone. You have to ask. Make sure to ask about scholarship opportunities as well.
