I'm filling in my Common App and I do not have extracurriculars, and I also suggest none. We haven't accompanied a club or worked a working job or such a thing organized like that. I do play tennis and disk golf with friends all of the right time-- could I consist of that? I've also babysat my cousin although not for the money. Can that count? If I enjoy bake can that go on there? Seems like a stretch but I truly have nothing else to list.
Admission officials are often desperate to learn what students do outside of class time, and not just through the same-old-same-old school groups and recreations groups they see on applications about 717 times on any given cold weather week-end. Which means that your baking, babysitting, disc golf and tennis are quite application-worthy.
Within the amount that is small of supplied in your applications (and/or using a split "annotated" resume where you add a sentence or two describing your assorted undertakings), you will need to give a little more information than merely the title of each and every undertaking, incorporating a little humor occasionally if it comes obviously for you. As an example, rather than saying, "Baking," you might have space for, "Experimental pastry cook for family members guinea pigs. (whom knew that chili sauce and chocolate frosting is so suitable?)"
The following is an old but when very College that is active Confidential thread on "concealed Extracurriculars" that may assist you to identify other pursuits that would be fodder for the "Activities" section of your applications.
