Financial Aid Concerns

I will be attend GW this fall as a freshman and my financial aid package has still not been worked out.
Here’s my story…
When I applied to GW, my parents had not filed for their 2014 taxes. Therefore, I had to use their 2013 taxes to create a financial aid package. Unfortunately, in 2014 my parent’s made $20,000 less and we added a dependent. This of course puts in a position to receive more aid. BUT, GW would not make a new package without an IRS Transcript for 2014 to verify these numbers. I BARELY received the transcript because it was unavailable to me for a very long time. My parents not only did their 2014 taxes late but they submitted them by mail, making even more difficult to get the transcript early. Now, I have submitted the transcript and am currently waiting for it to be uploaded.

What are my chances of receiving a completely new package? If I do receive a new package, will they probably just add more loans or increase the institutional grant?

Any advice and guidance would be greatly appreciated. Thank you!
