hoping for 700 cr

<p>last march i took the sat and got a 510 on the cr section. the following summer I studied a lot of vocab and took probably 15 practice tests. I only scored a 610 on the cr in october. I thought I was done with the sat for good. Since October I have probably read 10 classic novels, so my reading level is up to date and my vocab is strong. I took a 3 practice cr sections today and scored a 640. I haven't done any preparation other than reading since October. Do you think its possible and what techniques should I do to possibly score a 700 by the march 10th sat date? thanks.</p>
