<p>Grades, ECs, etc do speak to u as a person. It can show your interests, commitment to education, what you enjoy, where you excel, etc. If you have ECs that are religious based then it speaks to that. Sports, dance, math club, photography, all say different things- a combo of different ECs say something different/ more.</p>
<p>PS however, as @bomerr said, expand on what they know, to determine if they like you. Is this a person I want to have in my classroom? Do I want to counsel this person? Do I think they will get along with our other students? Those are questions that I think the ECs help answer.</p>
