Should I take Kelley pre-reqs at community college over the summer?

I was admitted Exploratory and math is my tough area. Should I take classes at a community college over the summer - especially math? Has anyone done this? Are there any classes that are particularly hard pre-reqs for Kelley that I could take over the summer so I’d be able to completely focus in on that class?

If you have scholarships see if that affects them. My understanding is if you take classes between graduation and the beginning of freshman year you are no longer considered a freshman for that purpose at some schools.
