Well, I've actually been reading it for just under a week now, on and off.
It's a
great book but, now I am part way through it, I would recommend anyone gunning for the CWNA to read the CWTS book as a precursor. It has made several of the early chapters in the CWNA guide so much easier to get through because of the background knowledge the CWTS Guide has given me.
I am up to Chapter 4 of the CWNA book now, having just this minute finished Chapter 3 and the end of chapter test. I thought I was struggling but I have just astounded myself by being able to calculate the EIRP, or what the mW is if the dBm is something else in the tests. That might be easy for some but maths was never my strongest subject.

I am thoroughly enjoying the learning experience, so much different from my MS studies... so refreshing.
