Using only one prep book. Is theree a way to increase your score to a 2400?

<p>My friend's cousin said she did it with only the ultimate guide (BB)</p>

<p>is it even possible?</p>

<p>(p.s. all I know is her first score was like a 1000/2400 and now it's like a 2300/2400)</p>

<p>And I know.. I should have asked her. But she kinda didn't tell us o.o</p>

<p>she increased her score from a 1000 to a 2300!? what! thats by far the biggest improvement ive ever heard of. either shes yanking your chain, exaggerating like crazy, or that book is like god. i mean, ive heard of big improvements but not like that</p>

<p>Woah… I find that incredibly hard to believe</p>

<p>She probably just quite 10% of the way while taking the test because she was bored out of her mind.</p>

<p>Or this is fake.</p>

<p>lol I kinda think it’s her messing with us (since she is going to an ivy league… I guessed I believed her XD)</p>

<p>But eh I thought well, why not? It’s the BB. The test writers wrote it!</p>
