Hi
Here is partially complete 70-462 Exam Guide which I will be updating soon.
I'll be taking the exam on 7th of Jan '13 (second attempt... missed 2 questions to get pass mark last time)...70-462 Training Kit Book is my main learning material.
I find 70-462 to be rather comprehensive but hopefully studying the book in details will help me to get pass mark 😉
Take care
Emil
