Navision 4.0 Development Exam

I have only been working with Navision 4 months andI have passed the 1st exam and unfortunatly failed on the first try of the second exam. : Also unfortunatly, the exams which have a base of 600 questions that are randomly scattered for each 100 question test was written by a MS guy who delights in making things tricky. :evil: Many of the questions in both exams are worded incorrectly or do not logicaly have an answer that is one of the choices. When I took the 2nd exam, I got the exact same question 16 times ( I went back and counted them during the end where you can review before submitting your test) Since I did not know that question it really hurt to see the same question 16 times - You can buy a book with a CD to study for either exam - the books from Time-Warner publisher for MS are $250(USD) if you are an MS partner and the book is very good. I remember that there were a lot of questions on the upgrade and how to set the versions also several questions on effiencey and the posting routines. Good luck to every one - I will try to look thru my notes from the test and class and see what questions I can recall.
