- Oval Stadium - Located at the back of the school where BoBoiBoy and Fang compete in the game of the sprint race.
- Canteen - Like other schools, there is also a canteen.
- So far the known rules are:
- In the staff room, there are warning signs that say "To the students, no entry" (Season 2, Episode 5).
When Gopal thought that PETAI will attack BoBoiBoy and the rest after capturing Ochobot, he suddenly drilled underground which causes to shake above and destroyed the school building, the shaking was only stopped by BoBoiBoy Quake.
- In the Season 2, Episode 12, the school was damaged by PETAI. But in some What Yaya Says episodes, the school is looking good and not damaged at all.
- This might hint that those episodes were created before the destruction.
