Are there any resume items which would make my college application really stand out?

Hi there! I would include anything that highlights your abilities in leadership, initiative, and teamwork. Those are the skills that will set you apart to an employer, and college should be considering you similarly. It sounds like you have all of the ingredients for a great application already - but take the time to highlight the attributes I mentioned and think about how it can apply to your studies and long term career goal!

In my experience, your well-roundedness makes you a great candidate! Admission teams really want to see a candidate that will be able to contribute not only in academics, but in other cultural aspects as well (music, sports, clubs, etc.). I would suggest that you take time to consider which one of your many activities could be a focus; as much as admissions want to see a well rounded candidate, they also want to see a candidate that has focus and passion so that they can feel confident that they are bringing on a student who will make a commitment to a career/major/etc.

When I was applying to colleges, I tried to tie my outside experiences with my major. I applied to a LOT of different majors (global studies, marketing, computer science, design) and while it is not required for them to be relevant, it definitely helps if it is. If it is general volunteering/extra curriculars, put them in! I wasn't the smartest student but I know for sure that it helps your application the more you put on. I applied to 13 schools out of high school and I got into 9. Some of the schools I got into are Boston University, University of California Santa Barbara, San Diego State University, and University of Hawai'i at Manoa (where I ended up choosing). I was involved in a wide range of activities, and some of the stuff I wrote down include Key Club, Dance, Band, Sports, and specific volunteer events that had an impact. Good luck in what you do!
