34 and just starting out.

Hi I am new to this board and in January I will be a LPN nursing student. I have been trying relentlessly to get into the RN program at the school that I did most of my pre-reqs but I keep on hitting a brick wall as far as getting into the program is concerned. Each year they have some new requirement. 1 year it was Algebra, the next year it was Chemistry, I have both those things and still have problems getting in. I decided to send multiple applications elsewhere and got into a trade school called Medical Professional Institute www.mpi.edu. I passed the NET and was interviewed several times before they made there decision. I am kind of leary now because it is only ABHES accredidated not National Nursing Accredidated. Are my concerns valid? I mean I am grateful I got this far but what if I can't pursue my RN after becoming a LPN through a trade school?
