COSMOS or classes over the summer & job?

I got accepted into the “Introduction to Engineering Mechanics” Cluster at UC Davis. However, I have also been offered a job as a camp counselor where I would be helping kids with robotics, basic programming, and mathematics. I would also take two classes that I am deeply interested in at a nearby community college. I can’t do COSMOS and the camp counselor/CC classes together, I can only pick one. Since I am currently a junior, this is the summer before my senior year, so which option would look best on college apps? Thanks.
