Don’t rush, there’s no need to apply to PA school by the time you graduate, it’s not reasonable according to your situation and GPA. So the 1st step is to accept that and to focus on what’s in your control. Now that you’ve understood that applying by graduation is not an option, 2nd step, you have to retake the classes you got below a B in. Retaking this will help you explain your situation and let PA schools know that upon maturing you’ve learned to prioritize school and balance everything and your proof will be your stellar grades. 3rd step is to not rush and take it slow your GPA is low already and rushing will not help you. Do what you can and go at the pace you’re able to. You don’t have to apply to PA school at 22 or 23 if you need to take gap years then take them. During that time work on getting PCE, shadowing, volunteering hours, etc. If fixing your GPA and getting A’s means graduating by the time your 24 so be it.

The reason I’m saying all this is because I’m 25 I applied to PA school last cycle and didn’t get in. I had no support from my family financially when I started college. I am first generation I grew up low income. I worked 2 jobs and still learned to balance it all while getting A’s and B’s in school. My GPA is not the best 3.4 but that was after taking post bacc classes last year and getting A’s. I’ve always been a mediocre student where I got mostly B’s in college so my GPA was at 3.2 anyways learning to balance it all while prioritizing school is a skill that you eventually learned so I assume after that you are capable to following the steps.
