How does Penn State's 2+2 program work?

Hello!

I was wondering if someone could breakdown how Penn State’s 2+2 program works. I am interested in pursuing Aerospace Engineering, and was also wondering if I can do this path starting at ANY campus, and ending at University Park? Are you also GUARANTEED to get into a major if starting at any of the campus’ and want to continue to University Park assuming you maintained a certain GPA? Also how are internship opportunities at the commonwealth campus’?

Lastly, which two campus’ are the easiest to get into (GPA and SAT wise)?

If you go to the sticky at the top of this page, there is info on the 2 + 2 program. I believe a lot of your questions will be answered in that thread @Ron124
