Jawbone,

It is tuned GDAE going from the bass to the treble. 7th fret on the G (lowest) string will be D, 7th on the D will be A, 7th on the A will be E.

The damn things do tend to go out of tune easily, it goes with the job! But the better the quality of instrument and quality of hardware, the less this will be.

Here is a link to some mandolin chord charts for you.

Glad to be of service!
