Question about superscoring?

<p>i just took the SAT and got
770 M
670 W
590 CR</p>

<p>I'm pretty happy with my math and writing scores. However, I wanna improve my reading score. So let's say i take it again and get a 700 in math and 650-ish in CR, with the same 670 in W will colleges care that my math dropped so drastically???</p>

<p>70 points at the high end of the score range is not drastic, as a couple questions could make the difference.</p>
