The sooner you get through NC1-NC7 (NC7=Foundations), the sooner you can apply for the CPNE -- sounds like you'll be within 10 credits of finishing with just those done. The wait for CPNE is about 6 months now, and will likely be longer by the time you finish -- EC just had a HUGE enrollment surge prior to the curriculum change on October 1. So you could do NC1-NC7 first, then do A&P and Micro while waiting for your CPNE date.
I'd start with either NC1 because understanding the nursing process is vital to the remaining exams, and that one covers it, or NC7, which is theory/history/how the ADN RN fits into practice, and is really different from the other exams. One of my coworkers is attending a traditional nursing school, and the NC7 material is what they do first.
Either way, welcome to the forum, and best of luck!
