My CCNA certification expires on July 13, 2010. I would like to take the BSCI 642-901 exam (expires on July 31, 2010) to count as recertification for my CCNA and count as 1 exam for CCNP. Would it even be worth it to take the BSCI 642-901 exam when I haven't taken any other exams on the CCNP track? Please help! I'm running out of time.
