Pre-reqs

I am 2 classes away from graduating with my bachelor's of health at WGU

I just need bio and chem for one programs requirement on top of that

I have 12,000 patient hours from military health working

And only about 100hrs of volunteering

I have letters of recommendations from 6 providers, 3 nurses and 2 front desk staff(they were lovely and I have to include them) as well as 3 of my previous leaders

Taking the GRE next month(so nervous)

Can I apply to a PA program after my GRE and just say im pending the 2 classes they need?? I am so nervous, I also feel like I may not measure up to the 3000+ other applicants that apply as I am almost 30. Less volunteering as Ive been caring for family and also my dog, who had passed. How difficult has it been for some of you to get in?
