Dh is using Tuition Assistance to finish up his bachelors. For some reason his school took his next modules tuition out of his pell grant.

My question is will Tuition Assistance pay it if it's technically already paid? I know like with MyCAA they said it wont pay for classes already paid for, so I was just curious if TA was the same way, or if we would probably get the check for the leftover amount once TA pays for the class. Dh emailed the school but I'm impatient
