Wow, thanks to everyone for the great advice.I think it is doable. I am 22 years old, no kids, and I chose not to work so I could focus all of my attention on my pre reqs. I know the science classes are no joke, so I have decided to put off work until I acually get accepted into the nursing program. (No I'm not rich and yes it's extremely hard being without a job, but it will be worth it in the end lol.)Thanks to everyone for the advice, I LOVE THIS SITE!!!! I don't start my science coorifices until next semester, but I will be sure to keep you guys posted on my progress.
