Good engineering programs?

I’m currently a junior and living in California. I’m interested in engineering so I’ve been looking for a summer program about engineering whether its research or just learning. However, I can’t seem to find one that I’m able to apply to. For instance, most of the COSMOS’s engineering clusters require a prerequisite of physics, which I have not taken yet, and UCSB’s RMP costs more than 10000 dollars. I’m sure I could find many programs at smaller colleges but I don’t know the quality of those, so they may not be worth it. I’m not looking for programs only in California. If there’s a really good one worth the money out of state then I would consider it.
