Frustrated with parking? MSSD students may want to consider purchasing a parking permit for main campus. If you are taking less than 12-credits this semester, you can purchase a "green" part-time commuter permit for only $15 for the year. If you are taking 12-credits or more, the cost is $50. Please keep in mind that this permit is not valid for the faculty only lot in Manayunk. For classes in PURC, you'll have to search for a spot on the street. More information about purchasing a parking permit can be found here.
