What Actually Works for OB/GYN Board Review
If you're staring at a mountain of OB/GYN material and trying to figure out what's actually worth your time, you've probably heard the name Emma Holliday floating around residency forums and study groups. She put together some resources that got picked up by people who are tired of wading through bloated question banks that don't match what actually shows up on the boards. The High Yield Ob Gyn Emma Holliday materials focus on the patterns that repeat, the high-yield topics that consistently make it onto exam blueprints, and cut out the rest of the noise. I've seen residents go from drowning in random UWorld and TrueLearn questions to actually retaining things after switching to a more targeted approach. Emma Holliday compiled her materials after seeing what her classmates struggled with on the CREOG and boards. The core idea is straightforward — she identified the topics that show up most frequently and built content around those rather than trying to cover everything equally. In practice this means she covers things like postpartum hemorrhage management, hypertensive disorders of pregnancy, and abnormal uterine bleeding in much more depth than low-yield subspecialty stuff like gyn oncology staging systems or complex infertility algorithms that barely get tested. I ran into a specific problem last year with a resident who was killing himself on question banks but still bombing practice CREOGs. He had read the entire ACOG guideline on heavy menstrual bleeding three times and could recite the algorithm, but couldn't answer basic clinical vignettes about it. The issue wasn't that he didn't know the material — it was that he was studying in a way that made the information stick to the page instead of translating to clinical reasoning. The Holliday resource has a different structure. Each topic comes with key concepts first, then practice questions that mirror the style and difficulty of what actually appears. After two weeks of using it alongside his regular question bank, his CREOG scores went from the low sixties up into the eighties. Not because he learned more material, but because he finally studied the right material in a format that matched the exam.
You can find the current version through academic distribution channels and some residency program libraries. Search for High Yield Ob Gyn Emma Holliday and you'll typically land on study group pages or institutional repositories. Make sure you're getting the most recent edition since ACOG guidelines shift every year or two and anything older than two years is likely outdated on management recommendations.
How to Actually Use This Resource Without Wasting Time
Here's where most people mess this up. They treat the high yield resource as a textbook and try to read it cover to cover. That's the wrong approach. The value is in using it as a supplement to your question practice, not as a replacement. The ideal workflow is to pick a topic, do 20-30 questions on it from your main question bank, identify the ones you're getting wrong, then go to the Holliday material and read only that section. This takes you from passive reading into active gap-filling, which is where actual learning happens. I've also noticed that people skip the self-assessment pieces inside the resource. Each topic block usually ends with a set of practice questions or clinical scenarios. These aren't optional. They're the closest thing you'll get to the actual exam format without paying for another question bank. Do them under timed conditions. Don't look at the answers immediately. Write down why each wrong answer is wrong — this single habit has been the difference between residents who memorize answers and residents who understand the reasoning, and it shows up directly on exam day when they hit a question they've never seen before. The resource isn't perfect. The gyn oncology section is thinner than it should be, and the maternal-fetal medicine content assumes you already have a foundation from your antepartum rotation. If you're coming into OB/GYN straight out of med school with no clinical exposure, this will fly over your head on certain topics. In that case, pair it with an ultrasound atlas and the standard Williams Obstetrics chapters for those gaps. It's not a standalone solution for everyone.

Common Pitfalls I See Every Year
The biggest mistake residents make is treating this as their only resource. The CREOG and boards pull from ACOG practice bulletins, SMFM guidelines, and some basic pathology that the high yield books sometimes gloss over. If you only study from one source, you'll miss the nuance on questions that test the edge cases. Keep TrueLearn or UWorld in the rotation. Use the Holliday material to sharpen your focus on the topics that matter most, not to replace comprehensive study. Another trap is reading the explanations without doing the questions first. Your brain will trick you into thinking you understand something because the explanation looks obvious after the fact. It's not the same thing. Always commit to an answer before looking at the rationale. This is painfully obvious advice but I've watched it happen repeatedly in study groups where people just read through the answer keys and feel productive without actually testing themselves. The resource cuts study time down significantly if you use it right. Instead of spending six hours a day reading random chapters, you're spending maybe three hours focused on the topics that actually move the needle on your score. The trade-off is that you need to be honest with yourself about which topics you're weak on. If you keep avoiding certain areas because they're uncomfortable, the high yield approach won't help you there — you'll just keep making the same mistakes. Pick your lowest scoring topics and run them through the cycle: question bank, identify gaps, read the focused material, retest.
There's also the timing question. Most programs recommend starting the focused review phase about six to eight weeks before the CREOG exam. The early part of the year should be building clinical foundation through rotations and lighter question practice. The last two months are when this kind of targeted high-yield work actually pays off. Start too early and you'll forget it. Start too late and you won't have time to close the gaps. The bottom line is that Emma Holliday's work fills a real gap in the OB/GYN study landscape. It's not flashy, it's not comprehensive, and it won't carry you through an exam on its own. But used correctly alongside a solid question bank and your clinical experience, it gives you a clear path through the material that actually matters. That's more than most people can say about the sea of review resources out there.
