My advice: find the program that has the highest entrance requirements in your region and meet their standard (for example, there are some programs that require chemistry OR biology and some that require both). While it will not be as easy as floating through school to meet the most lax standards you will be much more competitive.
Other advice:Work as a cna or a tech... The experience is valued by schools and jobs
Don't get in legal trouble... There is a forum at allnurses devoted to that filled with horror stories. Nothing worse than going through school than not being able to get licensed.
Be prepared to apply to more than one school, sure you have a place you want to go to, but be open to other options.
Public education is your friend. Unless you get a great scholarship, walking away from nursing school $70k-$100k in debt with only a bachelor's degree to show for it is insane.
