You can fix all of the speculation by having your seller give you the SKU number on the tickets. Call the OSU ticket office and have them run it to check if it is indeed legit. At that time, I would ask if the student has upgraded his ticket to "public" status. This cannot be done day of game and the student must do it. All tickets are now scanned going in to the gate, chances of you getting in without a faculty, staff or student ID will be next to impossible. Unfortunately, you don't deal with just the redcoats at the gate. The university has hired an independent security company to oversee these sorts of things. I hope this helps. Go Bucks!
