<p>I haven’t read the previous posts, but I did this question in 5 seconds.</p>
<p>Type 18 root 18 on the calculator, then press =…
It’ll give you 52 root 2
52 x 2 = 108.</p>
<p>Done.</p>
<p>the math part of Grammatix, or the whole book?</p>
<p>All of it, but especially the CR. The Math has no new strategies, but he dissects a lot of problems from the 1st edition of the BB. It’s just the way he gets you to view the test as a mechanical task - convinces you it IS nothing but a mechanical task - and how he calls himself a SAT Machine while he’s taking a test - that change your outlook. Professional test-taker attitude >> nervous college prospect attitude. It helps a lot.</p>
<p>okay, I’ll take a look. Thanks for your help :)</p>
<p>hmm, where can I find this Grammatix SAT guide?</p>
<p>Dunno if the books are still being sold, but PDFs are available if you look around.</p>
