Hi! Just wanted to reply and let you know you're not alone on here! I'm applying to both Regis and UC-Denver. I think the average prereq is somewhere around 3.7, but don't quote me, I could be misremembering.
Have you submitted everything yet? I'm working through a draft of my essay and waiting on one reference. UC-D just started using NursingCAS as well and their essay requirements are more specific than Regis, and I'm wondering if I'll be able to select one of two different essays for each school - we shall see! Good luck and keep us posted!
