So, I would advise against going to a post-baccalaureate degree from a private program b/c the cost is pretty disgusting. Disadvantage status, from my experience, and most of my friends is one of those things that only comes in handy for interviews.... and really nothing else (I mean really, when does not having money help?).
Alright, so you WILL be able to qualify for 2,750 in subs and 3,000 unsubs loans (thats 5750 = 1 semester, 11,500 for 2) for your 5th year and ANY undergraduate college will let you do this. College is a business, and they want your money. I would apply VERY early b/c many schools that give out random scholarships that have deadlines.
Also, depending on what your gpa looks like, you might consider going into a 2 year master's program where you receive a 15-18k stipend. Now you cannot get this for junk like physiology or physical therapy etc, but if you went to graduate school for chemistry or biology, and (usually you cannot tell them your intention of staying for 2 years) mastered out instead of pursuing the phd you could actually make money or break even. Unfortunately, medical school admissions is full of ******ed policies and many deflate or skew graduate school gpa's.
Post bacc programs such as Loyola's and Finch's are pricey. Oh btw, I still like Loyola, and if that school is your first choice, then by all means post bacc there.
