I am currently a university student (business administration) and trying to improve my Linkedin page. I remembered that when I was a freshman in high school, I went to Camp Kennedy Space Center and completed a 3-Days Robotics program. I also received a signed certificate.
My question is that since this is not actually relevant to my major, should I include it or not? If yes, which heading should I include it under as it is a participation certificate and nothing more? Thank you!
