Throughout my high school career, I have taken about 3 or 4 online enrichment classes every summer. I took them because I was interested in the topic and they relate to what I want to major in. Should I add this to my common app? and if I should add it, how should I put it on there? Should I list out the classes I took?
You can list them in additional information. It is better if you have some kind of certificate or proof, so include that info if you do.
