I hear the failure rate is around 90%.. I guess that puts me in the 10% group :-)
I read a book by syngress, did my own labs, bought a troytec studyguide (which i highly recommend!!) and used the resource kit for things i still didn't quite get. I don't know what I scored but I passed. I took 3 hours and was about 100-110 questions. I drank 4 diet pepsis to keep me on my toes. Some people don't want to take that long of a test but it saved me $400 and 4 trips.
