<p>I just got back from a Pton Info session and the rep (Director of Admissions) said they hate when you put "fluff" (he actually used this term) on your app. He said he didn't want you putting something you only did for an hour (I'm inferring a week but IDK), but instead include those ECs that you put a lot of time and passion into. He constantly mentioned the concept that applicants should be highly energized. </p>
<p>I think that it is ok to put some common ECs, as long as you have put significant effort into them and can show it.</p>
