The American Opportunity Tax Credit can be claimed 4 times per student.
If someone claimed you as their dependent and took the credit on your expenses, that would count as your time claiming.
You can see the refundable credit on your 1040 line 68, or 1040A line 44.
The amount can differ depending on your expenses paid for that tax year.
