GRUBER'S MATH - Too easy?

<p>I heard great things about this book, however, I've just started to use it and it seems ridiculously easy. I scored 510 Math my first try, and am now studying to bump it up to at least 600 (preferably 660). As bad as my score was, I got through all of the 101 Math Questions without difficulty, have just started onto the fractions bit, and am wondering if this is supposed to be helping me. I know how to add fractions, change denominators, convert mixed/irregular fractions, and deal with complex fractions. Will it get harder as it goes along or something?</p>

<p>Any experience with Gruber's?</p>

<p>…Does anyone know?</p>

<p>SAT math IS easy. but making a few mistakes can pull your score down quite alot. you should aim to get most, if not all the maths questions right. </p>

<p>Gruber’s may be easy, but its one of the more accurate non-collegeboard books for maths.</p>
