<p>^Eh,</p>
<p>In college, how smart you are really doesn’t have much bearing on how well you do after a certain point. Many of my friends who entered school with the highest test scores/greatest sheer intelligence are the ones performing fairly poorly compared to peers with lesser academic credentials. I strongly doubt that the OP’s lower range test score (with respect to Brown) is significant in predicting definite struggle. And a C in honors precalculus would speak more to a lack of effort or interest than a lack of intelligence, as many many unintelligent people do well in that class at their respective schools.</p>
