<p>On my common app, I left out certain ECs b/c I thought they were minor, i.e. random clubs that really won't make a difference. I had the chance to see one of my teacher recs, and everything in the rec is fine except my teacher mentions one of the clubs that I left out in the common app's EC section and an additional activity sheet that I attached (he just listed the name of the club, not any details). Will this raise any flags? It's just that I was part of the club when I asked the teacher for the rec, and I quit it later since I lost interest, but I didn't know that he would mention my activities in the rec (all teachers ask for student activities/interests when asked for a rec). Or maybe I'm just thinking too much into this? I already submitted all my apps and recs.</p>
<p>You are overthinking it 
I don’t think the adcoms will even notice. They are going to focus more on the sound of the rec, not all the details in it.</p>
