You’d be surprised what ECs colleges find interesting. My D applied to many colleges…all top schools. Her summer job was chicken sitting. We live in a city where quite a few people have backyard chickens. My D took care of them when people traveled in the summer. 3 colleges mentioned this EC in her acceptance letters. I think interesting things like this catch the eye of admissions people. We laughed a lot about this! Maybe you already have something unusual you do in your wheelhouse you haven’t really considered to be an EC.
