NVCC or Marymount??

I am looking for an accelerated program for 2nd degree people like myself. Currently I am a music teacher and I need to give my resignation notice by May 1st. So I want to pick a school that will allow me to start as soon as possible and cost the least amount of money since I am already in debt with college loans etc. I was strongly looking at Marymount and NVCC. I need to take my prereq's still so that will take longer but I'm concerned about waiting lists and/or not getting into the nursing programs. I really want to get started as soon as possible but I'm nervous about putting in my resignation without being able to start right away. I've done a ton of research and I know that this is definitely what I want to do (just wish I would have realized this before I got my music ed degree!). Any thoughts on Marymount and NVCC would be greatly appreciated as well as thoughts on waiting lists and getting accepted into schools. I always did really well in highschool with 4.0's or higher. College I got a 3.31 which is ok but I'm slightly older now and more responsible so the work load won't be a problem. thanks for all your help and advice!!
