Section View - South side of the gym
Level 1 is where the gym starts and is on a lower level than the classrooms and hallways of the first floor.
Level 2 is the level where most hallways and classrooms are located on the first floor.
Level 3 is where the second floor is and the gym's ceiling is the same as the second floor's.

Overall, I think you've done a nice job and your intentions are right. You just need to refine your approach to articulating your ideas.
