Query: Harder than the real thing

I had a limited amount of time to study for this SAT II since I was taking it just before finals week. This book not only allowed me to zero in on what I didn't understand with the diagnostic test, the problems in it were actually HARDER than the ones on the test. On the test day, not only was I secure, I was confident in my knowledge that I could beat this test! Math is not my best subject so this was a great feeling. I just took the test so I don't know how I did, but I would recommend this book to every person taking the test, whether or not they're math-inclined.
