My friend that is going through the Excelsior program with me, her roommate took the microbiology exam and passed on her first attempt. She followed the free content outline that excelsior has as well as using TCN module & CD from lisa arends on ebay. My thought is that if I can pass the A&P exam on first try, I could do anything. I am also waiting until 1st to purchase the text that Excelsior recommends for A&P. Good luck everyone - and let's keep each other posted.
