<p>If you’re in-state, you’ll probably get into UCB because they take everyone with similar stats. I had near-identical numbers as you when applying last fall, and unfortunately your GPA will be a weak point for the very top schools, Princeton included. The volunteering is great and I think it’s pretty cool, but it’s not going to make up for anything lacking in your application. As for whether it’s “Ivy-worthy”, I don’t think there’s such thing. 2 to 4 week stints in underdeveloped countries don’t cut it. </p>
<p>With that being said, I’ll finally answer your question and say that it falls somewhere in the highish “okay” category. It’s not going to help majorly but I can’t see it hurting you either. </p>
<p>Best of luck!</p>
