upenn v duke

hey! so i’m currently looking over colleges and while i’m far from set in stone about anything, i was wondering about pros/cons of penn and duke, and how they compare, etc? especially as far as financial aid goes, and also what they’re looking for (they’re both pretty vague about what they ‘like to see’).

i’m interested in majoring in chemistry, biochemistry or pre-med (most likely chem, tho) currently, so an analysis on either of them as far as sciences goes would be pretty helpful too.
