When does an undergraduate become an "upper division" student?

When the student has completed 59.1 or more course credits. All advanced placement or transfer credits placed on the Penn State transcript will count towards the total number of credits a student has accumulated, even if some of those credits do not meet the course requirements for graduation.  

Please be advised that a student’s tuition will increase when the Penn State transcript reflects 59.1 total credits. If the credits you are transferring or have transferred place you above 59.1 credits after the start of the semester, your tuition will increase immediately. You will receive a bill for the additional tuition in the first week of the following month.
