Passed on the first attempt and wanted to share a few tips:
Pro tip - You can run the videos faster than normal (Right click and change speed) - I ran at 1.5 or 2 times speed depending upon the material - it will save you time and these guys talk sooooo slow. This also give you time on the tough material to go back and repeat until you really understand it. It's sort of managing the technology like a personal tutor.
Go through the material as quickly as you can and get to the exams. Most of the real learning comes when you have to start answering the exam questions. Doing the exam takes a lot of time. Each exam takes 3 hours to complete and then 1-2 hours to review the results and figure out what you need to learn. The first few times you will fail, but stay with it, these are a little tougher than the actual exams. The important thing it to think about timing. At most, you can do 2 practice exams in a day, and that's all day. I would suggest dedicating Wed-Sunday on practice exams leading up to a Monday afternoon exam.
