How well do you know FM Transmission?

Genius!

WOW! You really know your stuff! Give yourself a pat on the back, and turn your pager off this weekend - you deserve it.

Not bad...

That's a solid effort. You still have a bit to learn (don't we all), but that's okay. Go find some more user manuals and devour them in your 'spare time'.

Getting there...

Look, you got more than 50% and that ought to be commended. Find yourself a good mentor and prepare yourself for a bit of learnin'.

Step away from the transmitter...

You gave it a shot, and that's a great thing, but you probably need to get a bit of help before you go near a transmitter.
