Yeah I actually had this problem last year too. I put my "top" 4-5 Ec's there.
Most of the time a secondary would ask for more information.
I had a CV that I included with a lot of my secondary applications..yes totally uncalled for but I figured they would throw it away if they didn't want it.
I also used the same CV for allopathic school cause after i turned in my AMCAS i realized there was bad grammar in the EC sections and you can't go back and fix that.
