I'm currently doing VCU's post-bacc right now. Long story short, fall semester was absolute hell. Hands down the hardest few months of my entire life, so far. But if you put in the effort and come out okay, a lot more opportunities will come your way for spring, to further help with your application. I'm extremely happy that I chose VCU's program over the other ones I was admitted to, now let's hope it pays off with an acceptance somewhere!
EDIT- what I said above refers to VCU's CERT program, not the other post-bacc program they have for those who don't have the pre-health requirements professional schools require.
