Wish I had a book like this last year when I was attempting to pass my exam(s), it is my goal for next year. I was really surprised by the size of it, being so thin, yet packed with useful information that will make any person just starting (or not) supporting cisco devices wished they had at their disposal for quickly finding the proper sequence when their memory doesn't want to cooperate with them and its much easier than finding the info through Cisco's web site or through the help menu on the device. This will definitely help with a quick tune up just prior to the exam. I've never used flash cards but I would probably say it would be very similar to that.

I posted this info on Certcities.com and one of the guys there asked if it was the same as http://www.amazon.com/gp/product/1587131595/002-0029014-1337631?v=glance&n=283155&n=193977&s=books&v=glance and it does appear to be very similar. Had I known about the other book before I would have got it too for my library.

I'd give it a thumbs up for a very good quick reference guide to everything I wanted to know.
