I'm going to be applying to grad school in the next few semesters, and I was wondering what impact (relevant) extracurriculars have on my application. So far I've presented at 3 conferences, published a paper in a peer-reviewed journal, am starting a chapter of Phi Sigma Tau at my school (I'll probably be president or vp of the chapter), and have been Apprentice Teaching under one of my professors for a philosophy course. How much of an impact does this have on my chances for admission, if any, and should I continue trying to pursue further extracurriculars if they do have an impact?
