How much time does ABOS Part II prep take?

Most candidates who pass the ABOS Part II oral exam dedicate 3 to 6 months of focused preparation, with a total time investment of roughly 80 to 150 hours. However, the distribution of that time matters more than the total. The biggest time sink is case list organization and summary preparation, which can take 60 to 100 hours if done manually. The actual mock oral exam practice — the part that most directly predicts exam success — typically requires 20 to 40 hours.

A practical preparation timeline looks like this: 6 months out, begin compiling your case list and organizing documentation. 4 months out, start writing structured case summaries for every case on your list. 2 months out, begin weekly mock oral exam sessions, ramping up to 2 to 3 sessions per week in the final month. In the last 2 weeks, shift to rapid review using your quick-reference sheets and targeted practice on weak areas.

The candidates who run out of time almost always made the same mistake: they underestimated how long case organization takes and started too late. By the time they finish their summaries, there is no time left for meaningful mock exam practice. This is backwards — the mock exams are what build the composure and fluency that pass the exam. Ortho Board Prep reduces case preparation time significantly by automating case summary generation, freeing candidates to spend more time on the practice that actually matters.
