Should I retake SAT? and Questions about Questbridge

<p>I took SAT twice. The first time, without any studying, I got an 1860. I received my scores for the second test yesterday; I received a 750 in math, 730 in reading and 650 in writing for a composite score of 2130. I am an Asian immigrant. Standardized testing has always been my weakness since English wasn't my first language. I don't know if I should take SAT for a third time. I'd really love to attend a liberal arts college! Please give me some advices!</p>

<p>Oh, furthermore, I applied to Questbridge program and am a finalist. I know I won't get matched, but I applied to Questbridge mainly because I'd like to apply to Williams for free through Questbridge regular decision. Is there a difference between the acceptance rate through Questbridge regular decision application and common app?</p>

<p>Thank you so much!</p>
