Currently a BM postbac, i know we're not taking apps for 2008 anymore. as for financing, mostly done through private banks though there is a small amount the federal government will give for 5th years.
BM will still accept applications, but they'll only be considered if there are still spaces left over after all the people who got their applications in by Jan 15 are admitted or rejected. Go ahead and apply, if it's worth $75 to you -- if you're an outstanding applicant, you might get in.
And FAFSA does apply, so long as you haven't already taken a 5th year of undergraduate work.
