Where to put Educational Summer Programs on the Common App?

Hey all,
Is there a general consensus as to where summer programs that don’t yield any sort of degree or grade belong on the common app? Like Summer@Brown (the non-credit version) or Explo? I was thinking of the Extracurricular section, but I’m not quite sure.
Any help is super appreciated.
Thank you!

Either that or additional information.

My D put them under “activities”, along with her part time job, sports teams, etc.
