Repetition is the motherhood of learning. Passed the exam a couple weeks ago on first attempt and agree with the other posts that it was challenging. I recommend creating your own spreadsheet of the 47 Processes and all the ITTOs. Create relationships between the processes in your spreadsheet. Review your spreadsheet FROM THE BEGINNING each day. Practice at least 500 exam simulations two weeks prior to your exam. Get a good night's rest the evening before, that's what challenged me the most. I was getting tired after 45 minutes into the exam with 3 hours remaining it becomes a multi-faceted examination of concentration and perserverance.
