Passed on 1st try with a 90%. Yay!
I studied the CWSP book thoroughly (and some of the CWNA 3rd ed. book), used the official online practice test (which gives you an great idea of the type of questions they ask), as well as read over some stuff on the internet (google search) whenever I needed more details or clarity.
It's not too difficult but you really need to understand each security method/protocol/policy/attacks and how they intertwine with each other.
Good luck to everyone else shooting for this cert!
Incredible score. Great Job!
