“over 40 hours of overseas volunteering”
“volunteering over seas for an immense amount of hours”
“A Certificate of International Service Learning (50+ hours)”
40-50 hours in a whole summer?! that is 1 week of work in the real world- hardly “an immense amount of hours”. Also, doing AP Psych over the summer just to bump up the # of APs will not help you even a little bit.
Seriously, an actual full-time job will be more impressive for your college app than your playing Gertrude Stein in Paris or being a drop-in do-gooder in a cool location over the summer.
