LPN or RN?

Hello, I am at a point in my life that I really don't know where to go from here, and I'm looking for some counseling and help. I am trying to obtain my RN (2 year) at my local community college but it seems so hard to get accepted.
I have completed all my pre-req's but don't have the grades( I guess to get accepted). My science's GPA is like 2.9. I got a C in CHM, B in A & P I and a C in A & P II. yeah . So I'm still going to apply for the May 2010 Generic program and see what happens. But if I don't get accepted, which most likely I will with those grades, I was thinking of going via LPN be done with it in 12 months and then apply to the LPN/RN transition program. BUt what I really want to know if I obtain my LPN licence will they overlook at my C's in CHM and A &P II and a few W's that I got ? and get accepted right into the RN program? Please help me with this. If there are any nurses out there that is reading my post. what will you do in my position? do I continue to apply at different RN programs or just go LPN? Thanks so much for your advise.
