How the letters are used
Rank a pad by its job. Letter stampers and diploma printers raise the homework pipeline. Desks matter when hires fail. Floor unlocks matter after the current floor's urgent pads are done. Colors and uniforms wait. Staff are ranked on their own board so a teacher is not compared with a printer as if they were the same object.
S tier
Player decision Buy the next higher letter before cosmetics on the same floor. If a cheaper pad is only the door to that letter, buy the door first.
Player decision Buy a newly unlocked free printer before bleachers or color packs. The 499 Robux Diploma Printer is a later shortcut, not the first printer.
Player decision Treat desks as urgent only while you are capped. Do not buy every desk on the floor before any stamper.
A tier
Player decision Buy them after the current letter stamper and any desk cap. They are strong, and they are not a substitute for the letter climb.
Player decision Buy it when urgent pads on the current floor are done and you already know the first upstairs stamper. Otherwise it is a stall.
Player decision Buy them in the middle of the run, after early stampers and a real student count. Skip them in the first session.
B tier
Player decision Add them between stamper buys once a healthy student count already fits.
Player decision Buy a piece early only when it gates an urgent pad. Otherwise wait until B-tier cleanup.
Player decision Pick these up when the main printer path is current and you still have coin left before cosmetics.
C tier
Player decision Buy them for a screenshot pass after economic pads on that floor are green.
Player decision Leave them until you are spending on purpose rather than because the button is cheap.
D tier
Player decision Delay until the current floor funds itself. Schedule edits that enable trips are not in this row.
Player decision Skip early. A neighbor's trophy shelf assumes their stampers are already finished.
