As the day begins we find out that the students have switched their rooms - something that Vice Principal Phil knows he is going to have to deal with. Things get off to a rocky start in Phyz Ed class as Tyler finds himself dealing with a safety issue. Meanwhile, an eager Yvonne tries to motivate her class on the dangers of industrialized food, only Rory openly declares that he is not interested. Later on, Rock Skool turns out to be a favourite, and the students are psyched over the competition between boys and girls. Vice Principal Phil then confronts the students about the room change, only to confirm that they are still very much in teacher mode and not respecting his authority. When the days marks are posted, many feel students feel they are unfair or unjustified, specifically Katherine who receives the first "F" of her life! It's been a long day packed with classes-only it's not over yet. Homework means the students get a chance to rock out!
