Whats the course and what is your level of forensics experience and your level of experience with EnCase?

I haven't taken the course.   EnCE is a pretty good cert though.  There are about 100 questions, I believe that are multiple choice.   The main portion of the exam is an actual case.   They send you a hard drive and you go to town on a somewhat realistic case.   You have to produce a good report. 

From what I have heard, it's probably not a good idea to take the exam right after the course if you haven't had Encase experience.   From personal experience, Encase is a tool that's very counter-intuitive if you don't use it every day.
