Yes, no double dipping. BUT
Since the credit is more generous than the 529 earnings exclusion; use as much of the tuition as is needed for the credit and the rest for the interest exclusion, even if you have to pay some tax.
Total qualified expenses (including room & board) less amounts paid by scholarship less amounts used to claim the Tuition credit equals the amount you can use to claim the earnings exclusion on the 1099-Q.
Example:
$10,000 in educational expenses(including room & board)
-$3000 paid by tax free scholarship
-$4000 used to claim the American Opportunity credit
=$3000 Can be used against the 1099-Q
Box 1 of the 1099-Q is $5000
Box 2 is $600
3000/5000=60% of the earnings are tax free
60%x600= $360
You have $240 of taxable income (600-360)
