Hi, having finished this program myself I think it's worth a shot. Based on both what I've read on here and people I know, I think the prerequisite grades mean the most. I do think being a male could possibly work in his favor (If I had to guess I'd think there were ~25ish males in my 150 person cohort).
I had an alright GPA when applying (a 3.5 and As in all my prerequisites) but had very limited healthcare experience. So, I think it's a toss up what they are really looking for. LMK if you have any more questions.
