What will happen if...?

My friend took his final exam, he been siting and playing until the end of the test then fill in his answer in the scan tron. The TA seen he looking around thought that he looked at someone answer then called him down on the first row to finish his exam. After he turn in his exam they hold on their hand and his coordinator email him want to see him before post the final grade. I just wondering what will happen is he in big trouble?
