Can't Pass the ERI / ATI Exit PN Exam HELP!!!!!

First of all I should give a little backstory to my situation as this is my first post. I was supposed to graduate from my PN nursing program (Mid-East Adult Center in Zanesville, Ohio), in 6/29/09. During my final exams after my 1st of 2 exams the ambulance was called as my instructors recognized that I was septic and I was taken directly to the hospital. Within 12 hours I was on a ventilator in complete renal failure on 24hour dialysis with a diagnosis of septic shock/ Ecoli. Needless to say, I missed my graduation date of 6/29/09 . But at least I was alive so I was happy for that. Unfortunately, I miscarried and I was almost 5 months along. I was in the hospital for over 2 weeks. I was able to schedule my last final (the OB/Peds I took when I was in shock I scored 90%) once I got home from the hospital. I took that exam (Med Surg) in mid to late July and I scored a 91%!I was so thankful! I received my diploma and scheduled the dreaded exit exam for a week later. I took the ERI PN exit (assessment) and bombed it with a 58% (63% is needed to pass so that I may be eligible to sit for boards).I didn't get a chance to see which questions I got wrong since they used rapid scoring instead of mailing it out to be scored so unfortunately I didn't get a paper with rationales or the areas that I was weak in or anything!I NEED HELP HERE!!! I have 2 more chances to take the exam and I want to be more prepared this time. The test consisted of 220 questions and I was totally unprepared for the question type and format, especially the nursing delegation and mental health questions. I have heard that ERI and ATI have merged and I made a call to their offices and was told that ATI offers a PN online assessment including rationales for 40$ and that it will give you access 5 times. Can anyone give me some study tips or books/online reading that you recommend to tackle this assessment. I have been through so much and will not let this keep me from my dream of becoming a nurse. Any help/ideas would be appreciated.
