PSAT scores: What should I do?

the PSAT score is only a rough estimate. i got an 188 (and a 44 in writing) when i took the PSAT's in my tenth grade year, i got a 2140 (720 in writing) on the SAT in my junior year, so there is a lot of time for improvement. there is also the ACT, which some score considerably higher on in comparison. it was probably just a bad day. for brown though you would have to get your scores up considerably , but again, don't give up.. there is also your GPA, extracurricular, and subject tests. a 750+ on a bio subject test could do a lot for you. so don't give up hope
