Our contest this year will be held in Gambrell Hall, which is located at 1700 College Street, Columbia, SC, 29208. On the link for the interactive campus map below, you should see USC's mascot Cocky pointing out its location.
You may park in any campus parking lot for free, as long as you park legally. In particular, you should not park in a reserved or handicapped spot unless you have a legal right to do so.
Do you have a large bus? - At the corner of Barnwell and Washington, you will see a fenced in parking lot. You should not park in this lot but you can park along Washington Street next to the lot. Be sure to pull off the street and up against the fence to allow traffic to flow. Here is a map giving you walking directions from the parking spot (A) to the math contest location (B).
