I failed the exam 3 x before passing it.
My first attempt was just to see how it is
My 2nd and 3rd attempt I was missing 1 or 3 questions to pass it, I complained heavily to Cisco on some of the grammar they had on the new CCNP exams/version, and they kept giving me free retake.
It's been almost 2 years I hope Cisco already fixed this exam, if not you'll fail it, it was just designed for you to fail.
I didn't really liked FLG I red the whole book it's way too much information that goes very in depth if I remember correctly.
Once you complete CCNP switch you're basically 50 % done with CCNP, as the route is easy.
My advise is check INE for different perspective on Switch.
