If you worked through school, you could easily have a few activities right there. I looked at my old AMCAS out of curiosity to see what I had put, and I had 14: 4 awards, 3 jobs, 2 ECs, 4 research, 1 community service. I left one blank in case I started my new volunteer activity in time; I didn't actually finalize it before submitting, but I had already organized the 14, so I just stuck with that. Some were condensed, like one research activity included the research, a thesis, and 2 presentations It's not as difficult as you think to fill up 15. And it's not "excessive" if you actually put the effort into doing all of those things. 🙄
