35F pivoting out of tech into pre-med. Advice on my 1-year sprint plan?

Quick background: did most of my pre-med pre-reqs in college, but graduated in 2013 with a finance degree instead. Worked in finance, then tech, got my MBA at Stanford GSB somewhere in there. But now I'm fed up with this dystopian AI bs. When I joined tech 10 years ago, it felt like people were still trying to make the world a better place, now it's just increasing shareholder value (often to the detriment of humans). Spent the last few months in existential crisis mode and after MUCH soul-searching, have decided to apply to med school.

As I mentioned, I'm 35, and I know I'm not starting med school for a couple more years no matter what. I'm prioritizing not wasting another application cycle over chasing prestige. Would love a top 20 school if it happens, but I'd rather get in somewhere good next cycle than delay for a reach. I plan on applying to next year's cycle (2027-2028). Here's my plan:

Past Credit

• 3.96 cGPA, 4.0 sGPA, but that's from 2013 (10+ years old)
• AP credit for bio and chem (chem AP had labs, bio AP didn't)
• 2 semesters ochem with labs
• 1 semester physics with lab
• 1 semester pyschology

Plan

• This Semester
  • Currently taking Khan academy classes on chemistry, biology and ochem to brush up on my science knowledge (any other resources I should be looking into?)
  • Take 2 advanced biology courses this semester (anatomy & physiology) at my local community college because it's free in my city
  • Start volunteering at a hospital to get clinical hours
  • Try to get some research under my belt
• Next semester
  • Take biochemistry through university extension program
  • Study my butt off for the MCAT
  • Continuing volunteering at hospital
  • Continue research
• Do all of this while working a full time tech job to save up money for tuition

Questions

1. I'm not doing a full formal post-bacc, just picking up the specific missing classes. Given my other pre-reqs are 10+ years old, do I need a real post-bacc to be taken seriously?
2. Plan is to self-study and try to crush the MCAT to offset the older coursework. Realistic, or am I kidding myself?
3. Is this all enough or am I still missing something?

Would really love any advice since I'm coming new into the medical space after 10+ years. Be gentle...auntie's got feelings too :)
