Shall this be enough?

im a sophomore in Massachusetts and i was wondering if it would be possible for me to even sniff at a college as prestisgious as Brown. Though from America, i just moved back here from London so i have the international experience going for me. i have a 4.4 GPA (throughout ninth grade) and i have only taken honors classes since the beginning of high school, so I’m not taking any AP’s as a sophomore. I run track/XC three seasons and I’m the president of my grade. I took the SAT and scored 1100 which i know is weak but it was my first ever standardized test and i am taking a PC review class in order to improve. Say i were to get my sat score up, does anyone think i have a chance?
