I’m planning on going to a summer journalism camp at BU this summer, and since I want to go to BU would this help me at all to put on my application that I went there, especially since it was at that school?
Ive read that many college representatives themselves have said that summer programs DON’T give you a leg up in admissions. However, it could make for a really good essay about why you want to go to BU! Also, if you’re planning to go into journalism, that demonstrates interest and commitment 
It can help in that you will be in a dorm and get to know (part of) campus. You can include that in your “why BU” paragraph.
