I would definitely consider taking any science classes again that you didn't do well on. ODU is preferential to anyone that's taken classes with them whether it be your prerequisites or not. I think that's what helped me this time since my GPA was exactly the same..
I was accepted into the concurrent program this year with a 3.8 GPA and 93 on HESI. Last year when I applied I was put on the waitlist even though I had the same GPA. I had just transferred to ODU from TCC so I didn't have a GPA with ODU at the time. I think since I took some classes at ODU it helped me this time around..
