You need a start and stop date (month and year for each) for your college education so reader can get some idea if you did standard 4 years right out of high school, or other.
Actual GPA is not necessary. (
edit: see Juked07's comment below)
I'd also recommend better visual organization of the resume (e. g. name personal info and major sections centered (slightly larger font size?), all individual entries and supporting info left margin aligned, and only start - stop dates right aligned). Alternative visual organization such as this (

e. g.
Penn State University
University Park, PA
Bachelor of Science in Economics (add month and year of actual graduation here; start and stop dates of whole college education can be right margin aligned on same line as Penn State University; I also used Penn State University instead of The Pennsylvania State University title since it is such a well known institution)
e. g. of more logically ordered contact info (centered header at top of resume with bolded line all the way across page just below it)
John Smith (slightly larger font size than rest of resume other than major section titles)
1200 Broad Street
Philadelphia, PA (zip code?)

(make sure this line ends properly right at right margin so it doesn't overflow onto next line if someone opens up electronic copy of resume)
Experience title might sound better if you say
Work Experience
