Hey CB'ers. I just need some advice. I took the March and May SATs... and for the March SATs, I did an average job, nothing noteworthy. I got a 1900

CR - 590
M - 670
R - 640

Then in May, I retook it again. I don't know how I did so well, because I didn't study at all... but my score went up by 220 points to a 2120.

CR - 650 (Reading's not my forte. lol)
M - 770
R - 700

Yeah, my math score is pretty good and I don't think I can do any better on it... but I don't know. Should I take it a third time? Just to improve my writing and reading score? Thanks everyone!

I think your SAT score is pretty good as it is, unless you're applying to a lot of Ivy League schools. If so, then you should study a lot and take it again, aiming for ~2250 or better.
