Vlsm

I just can't get it 100% I've read through MS book over and over and also read the Sybex book (which i found more confusing)

I'm studying for 70-642 I didn't find anything really hard except subnetting and VLSM I'm wondering what is the best way to understand 100%

I really feel stupid but the problem is that in real life I didn't really use a lot of subnetting so that's why I found it confusing.

So is there any article,book, doc ..etc that's really helpfull

Any help appreciated
