How big would you say the difference is between Barron's MathIIC and CB's?!

<p>I'm getting a little frustrated at Barron's practice tests (though I recently heard they are tougher than the real thing).</p>

<p>If I'm getting 750s on Barron's practice tests, will that ensure me an 800 on test day?</p>

<p>EDIT: Oh yeah, I'm wondering whether I should spend some time on math bringing it up to an 800 (I'm determined to get it) or whether I can go ahead and finish up the Physics material.</p>

<p>Dude... if you are getting 750 on Barron's just stop now. I can barely pull of a 600 on those, and I consider myself a good math student</p>

<p>yeah i juss got a 740 on the diagnostic test. some of the questions were pretty tough especially towards the end. hopefully barrons is a lot harder cause i'm trying to get an 800 haha. one more week !</p>

<p>I was getting around 700-720 on Barron's and got an 800. You'll be fine...</p>
