Put your left hand first finger on the 5th fret and your right hand first finger on the 12th fret.
Pull off downwards with your right hand first finger so that the 5th fret sounds, then hammer on the 8th fret with your left hand pinky.
Then tap the 12th fret with your right hand first finger and start again.
... pull, hammer, tap....pull, hammer, tap....

That one looks suspiciously like an error.
Can you tell me which lesson that is?
