u/Any-Quality-4700

I’m a year post grad with a human biology degree, when i graduated my gpa wasn’t that great it was about a 2.8. I really want to pursue my masters in public health but many programs require a 3.0 gpa and i would still need academic recommendations for which i no longer have connections to because i am finished with school. I currently work at a bank so im not really in my career field. What options do i have and what steps should i take to strengthen my resume? Should i aim for a certificate first or try to pivot to something else?
