How much do I need to raise my SAT to be accepted?

<p>I got my SAT scores back, and here were the results.</p>

<p>520 CR
670 M
620 W 9 essay</p>

<p>I am aware I probably need to raise the CR score, but I was just wondering if the other scores are good enough and what goal should I set for CR? I want to know if I should just prep for CR or all subjects. I tried looking online for average scores, but all the scores I saw were outdated. I plan on applying to FYC (Most likely). </p>

<p>Thanks. I'm going into senior year btw.</p>
