Plan to improve to 2100 for June SAT?

<p>Hey guys, I just got my January SAT results back with 710W, 660 R, and 640M, for a total of 2010. I really want to get a 2100 and 1400 double score for my next SAT in June. What do you guys think I should do to improve? Any help would be greatly appreciated since most of you guys are scoring much higher than me.</p>

<p>Also, I already used up all of the BB tests… should I buy the Collegeboard online course?</p>
