Advice

Did some serious damage to my gpa during undergrad and decided to do a DIY post bacc to try to up it a bit and get the required pre reqs. GPA has barely gone up and my moral has gone down. Currently taking Orgo 2 which is the last class I need. Retaking the MCAT in May (first attempt 501 :/). Was thinking about retaking calc, but I know it’s barely gonna do anything to bring up my gpa. Should I take the class to show and upward trend or just focus on my MCAT and DO schools? My plan is to apply this cycle and if I don’t get in then I will apply to my local SMP program with a direct link to a DO school. Dont want to give up on my dream of becoming a doctor as I feel like I’m already in too deep, I’m 25 and don’t want to keep wasting my life. Any advice helps.
