<p>While I have some standard ECs (employment as teacher, volunteering as teacher, volunteering at rescue mission, summer programs, research, science olympiads, other academic competitions), I've also done a lot of online stuff, but I'm not really sure what I should list on the common application. Here are some examples:
Project Euler (11-12, very high level)
Wikipedia Editor (11-12, moderate contribution)
Created Educational Website (11-12)
Created/Led USABO Study Group (11)
Various Online Classes (9-12)
Self-Taught Several Programming Languages (9-12)
Proofathon/Brilliant.org Competitions (10-12)
Website Intern (Application Pending)</p>
<p>Which of these would you put on an application? The only one I'm sure about it "created educational website."</p>
<p>If it helps, I'm a homeschooled junior. I listed some activities through 12th grade because I plan to continue with them.</p>
