Nursing School in Houston Admissions

I was originally majoring in law, but after living in a hospital for 6 mos with my granny and watching her suffer and succumb to heart disease, I have had the desire to go into nursing. I'm taking my prereqs, and plan to apply for admission for Fall 2013. I HATE math as it is not my strongest subject. I plan to apply to UTH, PV, AND TWU in the medical center. UT is the only one that doesn't require algebra. Just needing any advice on what I should do. Thinking about taking math in the summer. Has anyone ever done it, and is it a bad idea for those not great in math, or is it better to take in summer than reg semester.
