FRM difficulty

I just took CFA level 3 so hopefully I’m done with program. Based upon direct experience, can someone please advise the difficulty of the full FRM exam vs. a single CFA level (such as level two which I thought was the most difficult)? Does the curriculum overlap between the two programs make it significantly easier to study/pass?

Something similar was posted by another L3 candidate, thought this might interest you. http://www.analystforum.com/phorums/read.php?25,989354
