Activities Resume or CommonApp?

<p>I reported that I have attended several other things, all of which are true, on CommonApp. I had a talk with my college counselor but he didn't show it to me directly but all I saw was that I had Math Team and that was it. Do I need to write an activities resume even if I wrote everything on CommonApp? I reported everything and every one of those things were true. How do I start writing an activities resume? Do I need to contact the people that I've worked for?</p>
