<p>I've heard Princeton Review and Barrons mainly. For Princeton review, i heard that it doesn't go too in depth and is ok. Barrons I heard has small errors throughout the book. How about 5 steps to a 5 for chem? What is the best in your opinion?</p>
<p>5 steps is very good. Barron's is extremely tough, as is its wont, but is also good. Princeton is okay.
Go with 5 steps if you're just getting one, I think.</p>
<p>What if we're getting two.</p>
<p>Two- I'd go with 5 steps and Barron's, although you really can't go wrong with any combination of 2 different review books</p>
