Should i get this sat math workbook?

<p>In the math section of the sat the only questions that i get wrong, omit, or take an extremely long time to cover are level 4 and 5…sometimes level 3 problems. I found this book:
[Amazon.com:</a> Math SAT 800: How To Master the Toughest Problems (9781439200063): Dan Eiblum MSEd, Kimberly Noonan M.S., Nargess Memarsadeghi Ph.D., Michael Forman M.S., Matthew Konicki M.A.: Books](<a href=“http://www.amazon.com/Math-SAT-800-Toughest-Problems/dp/1439200068/ref=sr_1_1?ie=UTF8&s=books&qid=1284174644&sr=8-1]Amazon.com:”>http://www.amazon.com/Math-SAT-800-Toughest-Problems/dp/1439200068/ref=sr_1_1?ie=UTF8&s=books&qid=1284174644&sr=8-1)
would you guys recommend it?
I would still be doing CB math test but id use that book as an everyday thing…like 20-40 mins a day work on a few problems and review the answer.</p>

<p>this book is okay, but i found this one much more helpful to avoid silly mistakes on easier questions and get real practice with the harder questions. 5 SAT math practice tests.</p>
