Who I am, in two sentences.
I'm building a personal AI MCAT tutor because the prep landscape failed me when I was studying for it. I'm Sean Davis — I graduated from Yale in May 2025, I'm in a gap year at the Testani Lab at the Yale School of Medicine, and I took the MCAT on May 14, 2026.
That's the whole bio. The rest of this page is about what MCAT prep was actually like, what's wrong with the help that exists, and what I'm building because of it.
What MCAT prep was actually like.
Months of self-study. I watched the strategy videos. I ground through the practice. The score moved slowly, and in one section it wasn't really moving at all.
The work was happening in the dark. Every question I missed, I had a guess about why — but no one was watching closely enough to confirm it, name it, or tell me which weak spot to fix first. Score reports tell you what you missed. They don't tell you why you missed it, and they don't notice the pattern when you miss it for the same reason on twelve different passages.
I wasn't lazy. I wasn't unprepared. I was just working without feedback on the part of the work that mattered most — how I was thinking — and I knew it.
Where the help falls short.
ChatGPT will answer any question you ask it. It won't grade your reasoning against a real error taxonomy, it won't track your patterns across sections, and it forgets you between sessions.
A private MCAT coach would solve this. They'd watch your work, name the patterns, tell you what to fix first. Private coaches start at $2,000 for a full prep and routinely run higher, in batches you have to schedule around. Most pre-meds can't spend that. I couldn't.
That's the market reality. It's not a villain. It's just a gap.
Accessibility in medicine starts here.
The MCAT decides who gets into med school. The prep process decides who can compete on equal footing. Right now, personalized guidance — the layer that actually moves a score — is gatekept by price. Family connections and money buy a layer of feedback most students can't access.
The pipeline is improving, but one-on-one direction is still largely out of reach for students without network or money. That gap is what PreMedulla addresses. Diagnosis, pattern-tracking, and direction at a price a self-studier can actually pay.
Accessibility in medicine starts before med school.
What I'm building.
A personal AI MCAT tutor that runs the diagnostic and planning work in the background, so your time goes to practicing, reasoning, and actually learning. V1 covers CARS and Psych/Soc; Bio/Biochem and Chem/Phys come next.
If the story so far lands, the right next step is to get on the early-access list; the free CARS Diagnostic opens to that list first.
