I'm going to be a senior this fall.
This summer, I'm taking online classes related to my intended major, going to a summer program, and possibly volunteering at a refugee relocation center. When school starts, I'm looking to help our school become an EF exchange school.
I'm truly interested in these things, but I'm afraid that it's gonna look like I'm padding my application with last-minute things. I've done a fair amount of other activities throughout high school, but never found out about the exchange program until the end of junior year. This is also the first summer where I'm free to do stuff, so I'd like to take advantage of that.
Would adding so many activities seem off to admissions officers and if so, which ones should I not pursue?
