Wow, you honestly have every tool you need to ace this exam. I am very sorry to hear you failed decision making. It seems that is the section that people fail. Let me give you some tips.
(1) According to my own personal experience, Lindsey Jones 28 sims cd is the best tool. Study it again allover and master those diseases on there. That is a great tool.
(2) Now that you already have the pathologies from your exam, know that they will repeat about 7 of those diseases already. And then look at the list of what others have already posted on here. These are the diseases the nbrc brings. There is no new case again that they have. So, on here are all the list of all diseases that would be on every person's nbrc test. So, go and master them from your lindsey jones 28 sims cd.
(3( Just be relaxed and take your time to study these things again. You have all the tools. Remember that.
Goodluck on your next try. Feel free to email me (firstname.lastname@example.org) if you have any questions or need any further help. Let me know how I can of any further assistance to you.
