Typing teachers ban peeking at the keys because it helps today and holds you back later. Some help is a trap.

Some help is a trap precisely because it works immediately. Looking at the keys gets you through today while preventing your hands from learning where they are, so the thing that feels like assistance quietly installs a ceiling you will meet later. Any shortcut that removes the difficulty removes the learning with it. The question worth asking is whether a crutch is temporary or permanent.

Take the help you have come to rely on and go without it for one session. Cover the keys, close the notes, turn the answers face down. Expect to be slower, which is what learning it properly feels like.
