On the 10th day of Christmas

Amazon gave to me, a study guide to help with Finals and Certification.

As finals for my Injury Assesment class approach, I realize i'm one semester short of finishing school and sitting my Nationals. I think I am going to take the MBLEX as well as NCBTMB certification. This is partially the over-achiever in me, but I'm hoping it will give me good merit once I'm back in Scotland.
It's never too early to start studying and preparing for an exam, so why not start now.

Do you have any recommendations for Certification study guides?
What are you favorite methods of study?
