Since this is the only book that has real SAT subject tests, you must get this book if you want to take the SAT subject tests. The other book simply do not have questions like the real thing.
This is one of the workbooks my daughter used to prepare for her SAT subject test in Math Level 1. Although she did well on the real test (760), she didn't find this book particularly helpful because the 2 tests provided were overly easy and don't resemble the difficult problems that appear at the end of the real test. She finds Barrons and Kaplan books more realistic in that they reproduce problems closer in difficulty to those found on the real test.
Was exactly what I hoped it to be, Full of questions for practice, Albeit a bit short compared to the other SAT books(only 200 pages) I think that is still a fair bit of amount. for its price it was a great buy.
I think the study guide will be very beneficial to me. I believe I chose the right book...
Unfortunately, this book only has two practice tests. It is really tough to adequately prepare for this exam with so few problems. I recommend Barron's book instead.
