Help Finding A Summer Program?

I’m currently a sophomore and am looking for something to do in the summer. I realize its kind of late to start looking, but hopefully someone can help me? I’m a female and am interested in computer science. My family isn’t considered poor, but because of a turn of events, can’t really afford any of the expensive pre-college programs. I live in PA, but also have family in MA that I could stay with.
I was hoping to do something beneficial for my college resume (like a college course or an unpaid internship)…?
Thanks!

You could take a couple of MOOCs while doing something else productive (volunteering someplace, maybe). Be sure you follow through to completion and any certificate or whatever you get if you complete it.
