That's just silly. I doubt that things have changed all that much in the 5 years since I graduated university, and back then nobody cared where they sat. Just sit somewhere else and your non-problem is solved.
During my time in college, people only "cared" where they sat if they needed a power outlet for a laptop. And politely asking for a seat close to an outlet was a quick, easy process that I never saw someone say "no" to.
This thread is just odd. If the girl in question hasn't even said one word to the OP, why does he think she suspects him of attempting to cheat off her in the first place?
