I am a total newbie here and I apologize if some of my questions sound stupid.

So I have to take the Excelsior Anatomy & Physiology exam (Exam 506) in less than two months. I am not in a nursing program or anything like that. I just need this 6 hours credit for some other program that I am applying to, which happened to be same for many of you guys. I have purchased the "Fundamentals of Anatomy & Physiology by Martini/Nath" along with some DVDs and Course guide that was suggested when I was applying for the exam. However the book is very thick and I dont think I can finish it and also have time to review if I want to read every details. Also I think there are way too much information in the book than I need to learn. I purchased the practice exam too, and took the first set of 100 questions. I would like to know what is the best note/study guide/book out there that can prepare me for this exam within this short time period that I have? I have heard about cliff notes, lisa Larend's notes, Anatomy & Physiology ECE, and some others but I dont know which one is the best so I really appreciate it if someone could help me out here.
Thanks in advance.
