I am super excited with my essay. It’s about my passion for literature and writing and how it has shaped me throughout my life. However, I’m worried that admissions officers will read my essays and be skeptical because my ECs aren’t oriented toward writing and reading. My grades in English and on my AP exams do support this though. If they are always curious I have lots of writing I’ve done that I could send in to show them?? What do you think my chances are with this college? And how about Duke early decision?

Oh and for the 5pt scalers my GPA on that scale is a 4.5675. I just used the 6pt scale because Chapel Hill weights on 6pt.

Bump, anyone? : )
