The board isn't testing what you know. It's testing whether you can defend what you know under pressure, in real time, with a stranger asking the follow-up. Three tiers. Each one harder than the last. Each one making the next survivable.
Most board prep starts at the wrong end: hypothetical cases, question banks, things with no connection to the actual case list you submitted. PDI Med starts with your real cases — the ones the examiner has already read before you walk in.
Each tier eliminates one layer of friction and increases the pressure that remains. By Tier 3, the only thing left is the thing that actually counts.
Most preparation eliminates scutwork but leaves the physician unprepared for the actual experience. PDI Med eliminates scutwork too — compliance work, case formatting, chart archaeology. But what remains is designed to be hard. Each tier increases the pressure deliberately. By the time you sit in front of a real ABOG examiner, you've already sat in front of something like it. The shock has already happened. Safely.
Once you've reached 50% of the minimum required cases in a section, PDI Med runs your de-identified case data through the examiner vulnerability model — the same framework that predicts which cases draw the second question.
Every case gets a risk level. Not based on whether you managed it well. Based on whether it's the kind of case examiners probe regardless of documentation quality.
PPH, shoulder dystocia, accreta, route selection, operative delivery. These draw follow-ups regardless of how clean your documentation is. The examiner isn't reading your note to grade you on it — they're using it to find the case worth probing.
One probe trigger or moderate documentation gaps. May be where the examiner starts. Depends on what else is on your list.
Well-documented, routine category, limited examiner interest. Low risk does not mean zero risk — it means your cognitive prep time should be spent elsewhere.
The AI is not a quiz. It is an examiner simulation. It does not explain after wrong answers. It does not praise correct ones. It pushes. It asks the second question. It says "And then?" when you trail off.
The opening line is always: "I've reviewed your case list. I want to start with [highest risk case]. Walk me through your management of this patient." From there, the examiner follows real ABOG oral board cadence — your specific cases, not hypotheticals.
These are the exact follow-up lines used when a high-vulnerability case comes up. Every OB/GYN attending should be able to answer each one out loud, without hesitation, in the right order.
By the time you book a Tier 3 session, two things have already happened. The vulnerability map classified your cases. The AI Board Examiner found where your verbal defense broke down. With your OK, your Live Board Examiner receives both — without any PHI — as a brief before the session begins.
They don't start from scratch. They don't spend the first 10 minutes learning your case list. The session opens exactly where Tier 2 left off.
The session is 30 minutes on Zoom. When it ends, your Live Board Examiner submits their notes. PDI Med generates a post-session synthesis brief — what improved vs. the AI session, specific language improvements, remaining gaps before exam day, ACOG resources — and delivers it to you within one hour. That brief is the final deliverable before the real board.
The AI Board Examiner does not explain during the session. Everything that matters is in the debrief. It's generated from the session transcript when the examination ends — typically after 4 cases or 8 exchanges.
If you book a Tier 3 session, you can share this debrief with your Live Board Examiner beforehand. They open on the verbal gaps, not the strong defenses.
Join the founding cohort today for the case list — parser, compliance flags, encrypted vault, and ABOG export — at $49/month. The vulnerability map and AI Board Examiner are expected December–January, at no additional cost for founding members. The Live Board Examiner follows in spring 2027 as an optional, separately paid service.
Case log collection starts immediately. Board prep features unlock at 50% of the minimum required cases per section — enough data to generate a meaningful vulnerability model. Once these features launch, physicians who have reached that threshold in one section but not another will be able to request early access, with the understanding that feedback will be richer as the remaining cases are logged.
