<p>I scored a 560 in Math on the October test, what do suggest I do to acheive high 600's. Before the October administration, I was scoring in the 600's, but I would really appreciate any advice, such as certain books( Gruber's ?) to reach above 660's on the opcoming December test. I found satmathpro.com, and it looks pretty useful, so I've been doing some problems from there.</p>
<p>Any advice is appreciated, Thank you.</p>
