Opening the Gym in School II
To open the gym doors in School II, head to the Opensezmee Rail as soon as you begin the level. (This is the rail just above the long bike rack banks area). When you hear the second roll call bell sound (at 1:40), grind the length of the rail. Then head forward to get inside the gymnasium and do some serious calisthenics.
