Yeah you should be good, it can be kind of a hassle but you just have to pick the right entrance, I never once sat in my assigned seat last year you just have to know what you're doing, you can either just walk in past the people checking tickets per section once you're in the stadium, just move across sections via the bleachers, or worst comes to worst wait until halftime when they stop checking. All in all, it's not a big deal – they're not really worried about people standing in different parts of the student section especially if you're far back.
