He helped me prepare for my ABIM exam focusing on process and approach. We all know the information. Taking the test is a game, and Sean helped me figure out how to play it!

The ABIM blueprint is the American Board of Internal Medicine's table of what the internal medicine certification exam covers, with a percentage for each content area. In the January 2026 version, cardiovascular disease is the largest area at 14%, followed by five areas at 9% each, and the rest range from 6% down to 1% (ABIM blueprint).
Below is the full blueprint table, what the questions ask you to do, and how the test day, scoring, fees and dates work, each linked to the ABIM page it comes from.
The ABIM blueprint, area by area
| Content area | Share of exam |
|---|---|
| Cardiovascular Disease | 14% |
| Endocrinology, Diabetes, and Metabolism | 9% |
| Gastroenterology | 9% |
| Infectious Disease | 9% |
| Pulmonary Disease | 9% |
| Rheumatology and Orthopedics | 9% |
| Hematology | 6% |
| Medical Oncology | 6% |
| Nephrology and Urology | 6% |
| Neurology | 4% |
| Psychiatry | 4% |
| Dermatology | 3% |
| Obstetrics and Gynecology | 3% |
| Geriatric Syndromes | 3% |
| Allergy and Immunology | 2% |
| Miscellaneous | 2% |
| Ophthalmology | 1% |
| Otolaryngology and Dental Medicine | 1% |
Two notes change how you read the table. Hypertension is worth 5% of the exam, and all of it is counted in the cardiovascular figure, including the hypertension topics filed under endocrinology and nephrology (ABIM blueprint). And ten themes have no row of their own because they run through every area: critical care, prevention, clinical epidemiology, ethics, nutrition, palliative care, adolescent and occupational medicine, patient safety and substance abuse (ABIM blueprint).
Add up the top of the table and six areas, cardiology plus the five 9% areas, account for 59% of a typical exam. That is where most of your study hours should go. The small rows are still worth a pass, because a 1% area with two or three questions is easy points if you have seen the topic once.
Exam format at a glance
| Topic | Official rule | Source |
|---|---|---|
| Length | Roughly ten hours on one day. Four sessions of up to two hours each, three breaks sharing 100 minutes, and up to 30 minutes for an optional tutorial. | ABIM: register, prepare for and take your exam |

| Scoring | Standardized scale from 200 to 800 with a mean of 500. Pass or fail rests on the whole exam; content-area results are reported in standard-deviation units. | ABIM: how exams are scored |
| Passing standard | An absolute standard set by the Internal Medicine board using the Angoff method. You pass if your standardized score equals or exceeds the standardized passing score; the scoring page does not print the number. | ABIM: how exams are scored |
| Eligibility | Successful completion of accredited residency training and a valid, unrestricted state medical license in good standing; ABIM also lists alternative pathways. | ABIM: confirm your eligibility |
| Fee | $1,430 for the initial certification exam in internal medicine. Late registration adds a non-refundable $400. | ABIM: exam fees and refund policies |
| Results | Final results within three months of the last date of the exam in that discipline, by email and in the Physician Portal. | ABIM: register, prepare for and take your exam |
What the questions ask you to do
ABIM questions are single best answer, and most are written as a patient in front of you. The blueprint lists the tasks they test: making the diagnosis, choosing and reading tests, recommending treatment, judging risk and prognosis from epidemiology, and using pathophysiology to explain care (ABIM blueprint). Expect images and sound as well: photographs, X-rays, ECGs and recorded heart or lung sounds (ABIM blueprint).
Management questions dominate in practice. A stem will often hand you the diagnosis and ask what to do next, so knowing a disease is not enough; you need the order of steps and the point at which each test stops being useful. ABIM publishes the laboratory reference ranges it uses, and it is worth reading them once so normal values on the exam look familiar.
Test day: four sessions and three breaks
The exam runs about ten hours: four sessions of up to two hours, each with up to 60 questions, and 100 minutes of break time spread over three breaks (ABIM exam guide). An optional tutorial of up to 30 minutes comes first. Do the free online version at home beforehand (ABIM tutorial) and you can skip most of it on the day.
About 35 questions are new items being tried out and do not count toward your score (ABIM blueprint). You will not know which, so give every question the same effort and do not let a strange one shake you.
Pacing works out to two minutes a question if you use the whole session. Bank time on short recall questions so you can read the long cases with images properly.
Scoring and results
ABIM reports a standardized score on a 200 to 800 scale with a mean of 500, and the pass or fail decision is made on the whole exam, not section by section (ABIM scoring). The passing standard is absolute: the Internal Medicine board sets it in advance using the Angoff method, so you are not graded against the others in your sitting (ABIM scoring). The content-area scores on your report are in standard-deviation units and are best used to see where you were weakest.
Results come within three months of the last exam date (ABIM). In 2025, 86% of first-time takers passed (ABIM pass-rate report).
Dates, fees and eligibility
The internal medicine exam is offered on a handful of August dates. For 2027 they are Aug. 12, 16, 17, 25 and 26, and registration runs from Dec. 1, 2026 to Apr. 15, 2027, with a late window to Apr. 28 (ABIM exam dates). The exam fee is $1,430, and late registration costs an extra $400 that is not refunded (ABIM fees).
To sit the exam you need to have completed accredited residency training and hold an unrestricted medical license (ABIM eligibility). Once eligible, you have seven years of Board Eligible status; after that ABIM requires another year of training before you can apply again (ABIM policies). The policies we read set no fixed number of attempts, but each failed August costs a year, so plan to pass the first time.
Turning the blueprint into a plan
Start with a timed, mixed block of questions and sort your misses by blueprint area. Weight your weeks by the table above, then adjust for what the block showed: a 9% area where you score well needs less time than a 6% area where you are guessing. Our sample 8-week ABIM study schedule shows one way to lay this out around clinical work.
For one-on-one help, Sean Moazezi, DO trained in internal medicine before teaching full time, and Dr. David Wadie, board certified in internal medicine, also tutors the exam. Sessions are live questions with your reasoning out loud, focused on the next-step decisions the exam is built on.
