Pell grant and the 16 credits

[maxxor6868]

I been accepted into tesu and my credits are being evaluated. Originally I was going to take 16 credits in one term and graduate and just pay the difference in the cost of the flat-rate tuition. It is 4928-2115 (my max per term pell grant awarded amount) = 2813 plus the graduation fee about $3000. That would get me to graduate in December. Here the thing though. Can I not just maximize the amount of pell grant I get by taking 6 credits each term July, October, and January terms so I get the full pell grant for me 6345 - (4928 + 298) and walk away with an extra thousand dollars in my pocket and graduate in June? From what I saw on the site I would be graduating with my degree in June instead of December so really that what 6 months different but I would save a lot more money as well as not being stressed out by taking 5 classes in one term. Would this work and can anyone tell me if there are any cons to this plan? I cant contact the offices since it is the weekend but base on the financial aid award letter I receive and the information from their sites this seems to work out right.

update: I just realize that by taking 6 credits a term I do not get the flat-rate tuition and instead get per-credit tuition. Thus the only way this would be close is if I use the per credit system I would probably come out even.
