Opinion(s) on RH318 - Red Hat Enterprise Virtualization Course and Test (EX318)

I was hoping to get some perspective from folks that have attended the course.

Was the course worthwhile, in particular if you have to fund travel and lodging?

Was the test as challenging as the RHCE?  Did the class provide a signicant advantage towards the passing the exam?

I understand the question(s) are somewhat ambiguous.. I'm just looking for a gut feel from people that have attended the class and/or taken the exam.

Thanks!
