Only two years of a foreign language is required. However, many colleges prefer to see 3. For some majors, you will need to take up to 3 semesters of a foreign language, so the better foundation you have, the better off you’ll be.
If you are concerned about getting in with the lower unweighted GPA, consider applying with a summer start date as your second choice. This way, if you are denied a fall admission, they will reconsider you for summer. This would mean coming to University Park at the end of June and taking two courses prior to fall. It’s an expensive investment (about $8K OOS), but it’s a wonderful transition to college life and preferred by many students who would prefer to take a lighter load their freshmen year. Typically kids who are on the bubble will start in the summer – but recognize that a 3.8 could be on the bubble for Smeal business whereas a 3.4 could be on the bubble for a comm degree.
It seems like the new trend for kids wanting UP is to apply for DUS (“undecided”) with a summer start as a backup.
