go to fafsa.gov and fill out a FAFSA. From there, it will be sent to the college of your choice. The college will than contact you for further red tape paperwork...after all is said and done, depending on your income status, you will have financial aid....i get 700 per mo.
PS: don't let anyone discourage you. Age is just a number, and being in college at a later stage in life is very admirable, because you're honest with yourself...there are so many people who say "im too old" or "its not for me"...i think its wonderful you want to pursue healthcare: age is only a good thing, no one wants to trust a 19 yr old bar hoe loooking bimbo *like me* with a needle, right!
