<p>Your application is competitive provided you raise your standardized test scores. Take the ACT: people who generally do well in school usually do well on it, versus the SAT, which is more all over the place. If you score well on the ACT, you also don’t need to submit subject test scores at UPenn, which is an added bonus. In short, if you raise your test scores, you will definitely have a shot (especially since you are a first generation college student). Also, since the Model UN is (in my opinion) your strongest leadership position, I would play it up and talk about how dedicated you are to the club. Best of luck!</p>
