Should I take the new SAT?

I recently did the old sat, yet only once. I recently received my scores, a 600 in CR, a 670 in Math, and a 740 in writing. I was pretty disappointed, as I thought I had done much better in CR, clearly not though. I’m aiming for the UC’s primarily and i know this isn’t enough, but should I take the SAT again?

Why wouldn’t you? Try the ACT, too. Some people just do better on it.
