JATA pre-hire test

I am preparing for the JATA pre-hire exam. I had experience 12 yrs ago to work on the hospital side with the JATA CDMP program. I have been out of the hospital setting since that time. I remember some of the information we focused on at that time but some of the info is fuzzy. On the hospital side, this was the most enjoyable, rewarding position I have ever had in my long nursing career (this year is my 40th year nursing class reunion).
I have had several phone conversation and exchanged a number of emails with the JATA recruiter and also had a facetime interview. I have been given the opportunity to step back and take some time to prepare for this pre-hire exam.
I would appreciate any ideas and direction re the topics I need to focus on in preparing for this test.
