Built with a practicing OB/GYN

Prepare on your cases,
not someone else's.

Half of the ABOG oral is built from the de-identified case list you submit. Every other AI prep tool drills you on generic, synthetic scenarios. OBMOB ingests your real list and examines you on the cases you'll actually defend.

You already keep a HIPAA Safe-Harbor de-identified list for ABOG. OBMOB reads that list. No charts, no PHI, nothing new to scrub.

Topics tested
Antepartum infections 8.0 Fetal growth 8.5 PPH & inversion 8.5
Model answer
Pyelonephritis in pregnancy: admit for IV hydration and IV antibiotics (ceftriaxone) until afebrile ~24-48h, then a culture-directed oral agent, with nitrofurantoin suppression for the rest of pregnancy given the recurrence risk.
Strengths
Systematic, correctly dosed uterotonic ladder for PPH with escalation to balloon tamponade.
To improve
Didn't state nitrofurantoin's mechanism, or the patient's Bishop score before the induction decision.
Scoring is grounded in credible, verified sources (ACOG, SMFM). Still, this is AI-generated feedback; exam practice, not medical advice.

Questions, answered.

Everything you need to know before your first mock oral.

What is OBMOB?
OBMOB is AI-powered preparation for the ABOG OB/GYN oral certifying exam. You drill realistic mock orals with a voice-AI examiner, on your own de-identified case list or on structured ABOG-style cases, and get a scorecard after every case. On paid plans you can practice as many times as you want, any time.
Who is it for?
OB/GYN residents and fellows preparing for the ABOG oral certifying exam, and recent graduates who want realistic, repeatable practice without having to schedule a human examiner every time.
How does a mock oral work?
You start a case, your own or a structured ABOG-style one, and the voice examiner takes you through it one question at a time, with no hints or coaching, just like the real room. Say “I’m finished” (or set a time limit) and your scorecard appears.
How am I graded?
After each case you get a scorecard: dimension-by-dimension scores, your strongest and weakest moments, and a model answer so you can see exactly what a strong response sounds like.
How much does it cost?
Start free: 3 full voice mock orals on your own cases, no card required. Beyond that, Pro is $79/month and Premium is $129/month (pay quarterly for ~5% off, or yearly for 2 months free), a fraction of what traditional oral-board courses cost, and you can cancel anytime. See the full plans below.
Is OBMOB kept current with the exam?
Yes. Every case and question is built around ABOG's published content areas, and we re-align to each year's bulletin, so you're preparing for this year's exam, not last year's. We're independent and reference ABOG's public materials only.
Is OBMOB affiliated with ABOG or ACOG?
No. OBMOB is an independent exam-prep product, not affiliated with, sponsored by, or endorsed by ABOG, ACOG, or any certifying body. Our cases and grading are aligned with the format and content expectations of the ABOG oral, but we are not connected to them.
