Query: The best book to prepare for the SMS test! (70-086)

I took the SMS test before reading this book and I didn't pass. I had read other books but although they provided general knowledge, they were not specifically designed for this test. After I read this book I was able to pass the test. I highly recommend this book to anyone seriously considering taking the 70-086 test.
