From pupil to shah.

Pupils are all puzzles with a mate in 1 and 2. The tactics finder rates all others by points: for every further move of your own that has to be found (a quiet move counts more than a check or a capture; recaptures, forced moves and the mate do not count), a quiet first move, a sacrifice and when Stockfish does not find the move at a low search depth yet. The rating ranges are a rough guide.
