Missing one rotation!

Hello everybody out there

I did not finish RN program (I had to drop 2 months before graduation). I need Pediatrics and Pediatrics rotation only, in order to challenge the California board for the NCLEX-PN. Can anybody tell me if there is a way to get only this class in California (South) without going back for LVN program? LVN programs are costly, they last between 10 to 12 months full time and I am not young (only at heart!). I just became CNA.
I really hope somebody can help me, I have been trying really hard to find a solution.
Thanks a lot
