Barrons Prep book

<p>hey im a senior planning to take the sat2s in math 2c, bio, and chem.
and i have been working on them with barrons' prep books..
i find the questions from barrons hard..lol
so i was wondering how close the questions from Barrons' sat2 are compared to the actual collegeboard subject tests.
someone told me that barrons has tougher questions....is that true for all subjects??
thanks in advance for your replies.!!</p>

<p>Barrons is generally more difficult/contains much more irrelevant information than the actual test, Princeton Review is about the same difficulty, and Kaplan is uselessly easy.</p>

<p>is that for all three subjects or just math???</p>

<p>I'd like an answer to that as well, I'm using a Kaplan Lit book, and it seems pretty hard to me.</p>
