The course used to be in a hard shelled case that you could stand up. The binder is a bit more of a challenge never the less it's still possible to make a wall with the binder which blocks the paper on the desk from direct view. Use the mirror to see the paper. You'll look like you have your arms around the binder.
The whole idea is you only see the star with the aid of the mirror like using a periscope. to look around a corner.
