should I wait for the 2nd blue book?

<p>...which comes out in a month (in the middle of summer vacation), or buy the first BB? is the first one perfectly useful for today's SATs? Or do you guys think the updated (after 4 years) one will be worth the wait? or maybe it's worth it to get the first one, study, then buy the 2nd one when it comes out?</p>

<p>from what i understand, the new book has three new tests that the old book doesn’t. I’m not sure if anything else has changed substantially, so it really doesn’t matter.</p>
