This Clean the School! beginner guide starts at the exact Roblox experience by Fourteam Extra: learn the controls before moving items, work one visible School area at a time, and use the game's own placement and progress cues instead of guessing locations.
If one reset does not change anything, stop repeating it: rejoin the exact experience, confirm the control with one visible object, and compare what you see with the documented School milestone checks before trying again.
