In a real chess position, where the knight must go is the easy part because there something interesting to do there (like capturing a piece). The problem here is that the chessboard is empty, so it's difficult to remember where you should go.
The interesting part is finding the knight trajectory, reading the notation is boring and easy.
(If the point of the exercise was to read the notation, it should be a different game, like clicking that square as fast as possible.)
