You, your friend and her parents need to understand that neither the camp nor the physical rehab place will give her “some special it”. Either will only be a “defining EC” and help her application IF she can show that she has taken the experience and done something with it. The majority of applicants to Colorado College will have done something similar. She has to go beyond ‘I learned so much’ or ‘it changed how I understand things’ and show how it changed things for her, and (crucially) what she is doing with that change.
You ask “How does tutoring, lifeguarding, being a member of a few highschool clubs(not very active), and running jv xc look at a school like colorado college”, and the answer is how do they fit into her narrative arc of who she and where she is going? Part of the job of college applicants is to bring together the threads of their life and make something of the result.
Also, you keep going on about how ‘she just became eligible’, which I take to mean that she has just turned 16, which makes her a pretty young junior.
