What Do the Tier Rankings Mean in Our Clean The Library Tier List?
While ranking all the Classes in Clean The Library for this Tier List, we made sure to factor two things: How strong each Magic multiplier is and how much each Class perk speeds up the overall progression and clear time. Since this game is designed in a way that you can collect tokens whenever you successfully complete a stage, we did not factor in how difficult it is to purchase a class. This just means that as long as you choose the abilities best suited for your gameplay, you'll be the Flash of cleaners in no time.
- S Tier (2) - Class with the biggest boost to your most useful Spells (Magnet/Glow) and/or bonuses to movement speed that are useful from start to finish
- A Tier (2) - Class with a significant boost to your most useful Spells (Magnet/Glow) or big movement bonus
- B Tier (1) - Class with a small boost to movement speed and an ability multiplier to less useful Spells (Scan) that might be ok at the start of the game
- C Tier (1) - Class with a tiny boost to carry capacity

Which Class Should Beginners Choose in Clean The Library?
When it comes to the Class Beginners should choose in Clean The Library, keep in mind that completing the Grand Library nets you 2/4/6 tokens for Easy/Normal/Pro mode, so you could do one run on Easy, as you don't have to worry about book order, to unlock the Librarian for the added Speed/Carry and scan.
You could also opt in to do a Normal run or two, Easy runs, then pick up Athlete, as the movement boosts work even before unlocking spells. Athlete is particularly useful if you plan on not going solo, as the early boost works as soon as you load in, whereas the spell boosts still require at least a couple of sorted rows so you can unlock the spells in the first place.
Then once you're used to the game, slowly grind towards Sage and ultimately the peak of classes - Grand Librarian.
Now that you know which Class to aim for, you're all set on your journey to speedrun this game like a person possessed.
