What do I do with my Summer

I'm an electrical engineering student and I just realized I have to wait until next Spring to graduate instead of Fall because there are no four credit electives I can take during the Summer and I don't have the GPA to get a credit for independent study.

Anyways, how do I make the most out of my Summer? My gpa is not great, should I take bullshit classes or retake a class? Should I join a club? I think it's too late for me to secure a Summer internship.

But like I said, my gpa is not good. The current term might help me out but as of now my overall gpa is 2.75 and my UCF gpa is 2.37.

Any advice would be greatly appreciated, even if you're not familiar with the college of engineering.
