Has anatomy and physiology really changed in the last couple of years? Probably not.

You should be fine with the Martini text, but in all exams, my advice is to follow the EC exam content guide -- let that information guide your learning. If it doesn't seem like the Martini book is working out, switch it up. You probably won't know until you start. I also recommend the EC practice exams -- well worth the $65. Good luck on your exam.
