Using multiple review books

<p>Well, this “genius” at our school apparently uses multiple review books for every standardized examination he takes, SATs, SAT IIs. He uses Barron’s, Priceton, Kaplan, etc… and goes through them all.</p>

<p>Is this stupid of him or does it actually help? It seems to go against what most advocate here and is looked down upon here as well, idk.</p>

<p>What is your take on this?</p>
