SAT CR 710 Retake? and other questions plz help!

<p>Hi, I received a score of 2300 yesterday.
CR 710/ MA 790/ WR 800 (80M 10Essay)</p>

<p>Should I retake the test since my CR score is too low?
I made so many careless mistakes on sentence completion section.
Also, I am quite agitated b/c my friend got a 2390.</p>

<p>what do you guys think?</p>

<p>Also, is it true that colleges don't care much about the writing section?
then, my score is 1500 for CR+MA which isnt that high...</p>
