lvn-rn program problem...pls help...

So i have a slight problem hoping for someone for guidance. i just finish lvn program and want to do a lvn-rn bridge program. i have already taken all of the pre-req in 08 but i have repeated 2 of the science courses, and the repeat grades are C including the other science classes..i know i was young and was not serious about it at that time, but i am very much so now. ANyways, with those grades and my situation hardly any program will except it. I am willing to repeat all the science classes and get a better grade, but my problem is that i dont want to wait until my science classes expire( in 2013) for me to be able to apply to a program. because a lot of program DO NOT take repeat classes. So what option can i take. should i repeat all my science classes @ a different college and when applying to a rn program i just use the recent college transcript and not use my old college transcript? but dont they expect you to put all the transcripts from all the colleges ive been to? or is my only option is to wait until my old science classes expire to start over from there? pls and thank you for your help.
