Series 6 and 63 exams

[JoeBlazer55]

I'm going to be taking mine soon and I was just curious how difficult they are. Did anyone have a problem passing theirs or should I be ok as long as I have a general understanding of the study manual? I recently passed my property and casualty test on the first try so I feel if I could do that I should be ok with the 6 and 63 since they are similar types of tests. Any thoughts?
