<p>Dang these questions are truly hard. But anyways whats a good guildline precentage of getting those questions right to be on a way to score 750+ on the W and CR and a 800 on m. Is getting 70%-80% right good, cos all these q's are hard level stuff.</p>
<p>I think Barrons 2400 is very good if you are aim high grade, Grammatix is just excellent like another Math teacher. Princeton Preview is OK (I mean good). If you love solving Math, Gruber's is very good indeed. Its Math section is much better than Reading. I read it very often like I read my Statistics textbook. :)</p>
