If I was to register for CCO's early 2013 PMCC course, would it be ok to use CPC 2013 manuals I've already pre-ordered from AAPC for your course? Also, I have Carol Buck's 2012 textbook and workbook. Would it be ok to use that , or would I have to order 2013 books, and do the textbooks (except manuals) come with the CCO course, or does the student order that on his/her own? Thanks.
