Took my test on Friday and failed. I walked out feeling pretty terrible about how I did and the results that were given to me bore that out. Failed by 5 points (assuming that 70 is a pass).
The test was pretty difficult. If you're using the Whole Enchilada I would recommend that you find a secondary study source because David's study exams are really easy compared to the actual exam. If you do stick to the UWE, I recommend that you completely understand the concepts that are taught because the test isn't a measure of how good you are at memorizing things.
The worst part is having to wait 180 days. Already have it marked on my calendar. If there is one thing I can say is to take 3 solid months to study. You're going to need it.
