I have the book made by Tom Carpenter and have used it for passing 70-432. I had another book too and find that Tom Carpenters book goes a bit more into details with the stuff at least for 70-432 than the others I have seen.
I am going to start on 70-450 but from what I have found on the net, this book isn’t deep enough – you have to work with the program. But it seems that it the only book available so I will stick to it.
