Does the edition of a prep book matter?

<p>My cousin gave me his Barron's Maths level 2 prep book (8th Edition - 2009). I was wondering whether preparing using that book would matter? Will I miss out on key things if I don't prepare using the latest edition? To my knowledge there haven't been any recent changes to the SAT II subject tests so it shouldn't matter right? </p>

<p>Not really. Unless the format of the test has changed, and as far as I know the Math Level 2 has not.</p>

<p>You should be fine with that. Barron’s books often change after 3 editions, so I think this would be similar to the 11th one anyway.</p>
