you know when you tune your E string you hold the 5th fret to check it with the A? You do the same thing, but hold the 7th fret rather than the 5th, and when your E string matches with your A, you got it right. When you're in drop D, it should also sound like the D string, just lower in pitch.... or you can get a tuner and hit the 2 flats button, just stick witht he 7th fret tho, that's the easiest way.
