How should I continue?

My name is Jake, a DIY post-bacc student at a medium sized university. I got a 3.0 uGPA in Biochemistry due to a terrible freshman year (<1.0) with a 3.2 sGPA. A 3.8 gGPA in Health Admin. Now a 4.0 in my 12 credits of post-bacc courses. I got a 28 on the MCAT initially, retaking in June. I have three years or research experience, working full time as a lab tech for two. With my non-competitive grades, how should I continue. I’ve taken so many classes that taking additional courses barely influences my overall GPA.

I appreciate any replies and all the help.
