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!

Internal medicine board review works best when it follows the exam ABIM actually writes. The certification exam is up to 240 questions over about ten hours, and its blueprint says how much each specialty is worth: cardiovascular disease leads at 14% (ABIM blueprint). In 2025, 86% of first-time takers passed (ABIM pass rates). The point of review is to land safely on the right side of that line without giving up the sleep a residency schedule already takes.
This page lays out the exam, the blueprint, a sample eight-week plan for a working resident, and how one-on-one tutoring compares with a course or a question bank on its own.

| Questions | Up to 240 single-best-answer questions, up to 60 per session; about 35 are new questions that do not count toward the score. | ABIM Internal Medicine blueprint (PDF) |
| Scoring | Standardized scale of 200 to 800 with a mean of 500. Pass or fail is decided on the whole exam against an absolute standard set by the specialty board; content-area results are reported separately. | ABIM: how exams are scored |
| Passing standard | An absolute standard set by the ABIM Internal Medicine board (Angoff method), not a curve: everyone who meets it passes. | ABIM: how exams are scored |
| Eligibility | Completed accredited residency training and a state medical license in good standing with no restrictions (other pathways listed by ABIM). | ABIM: confirm your eligibility |
| Fee | $1,430 for the Internal Medicine initial certification exam; late registration adds $400. | ABIM: exam fees and refund policies |

What the blueprint says to study
ABIM publishes the share of a typical exam given to each content area (ABIM Internal Medicine blueprint). Read it as a budget for your time:
- Cardiovascular disease, 14%. The single biggest area. Hypertension alone accounts for about 5% of the exam inside it.
- Five areas at 9% each: endocrinology, gastroenterology, infectious disease, pulmonary disease, and rheumatology with orthopedics, 45% together; with cardiology, about 59% of the test.
- Hematology, medical oncology and nephrology at 6% each.
- The small areas, from neurology and psychiatry (4%) down to ophthalmology and ENT (1%), are worth a pass through the high-yield points, not a week each.
The blueprint also says questions in any area may touch critical care, prevention, clinical epidemiology, ethics, nutrition, palliative care and patient safety, and that most items ask what a physician does next: diagnose, order and read tests, treat, judge prognosis. Expect photographs, radiographs, ECGs and recorded heart or lung sounds.
Why internists find the ABIM hard
Most residents know the medicine. Sean Moazezi, a board-certified internist, puts it this way: the difficulty of the exam is not the concepts, it is that the answer choices are graded very close together. Two options are often defensible, and the points go to the person who can name why one is better for this patient today.
That changes how you review. After each block, look at the questions where you were down to two choices, not only the ones you got wrong. Write the detail in the stem that should have broken the tie: the patient’s age, a lab trend, a contraindication, what was already tried. Over a few weeks the same tie-breakers repeat, and that list becomes the most useful thing you own going into the exam.
Sample 8-week ABIM Internal Medicine schedule alongside clinical work
Sample schedule
Sample schedule for illustration only. Not a real student, not real data. Your tutor builds your actual plan around your practice-exam results and the time you have.
Sample 8-week ABIM Internal Medicine schedule alongside clinical work: 8 weeks, about 2.5 hours a day, 6 days a week. One day off each week.
A typical day
| Block | Hours | What |
|---|---|---|
| Question bank | 1.5 | One timed block of up to 60 questions on days off, 20-30 questions on work days |
| Content review | 0.5 | Missed-topic review |
| Anki review | 0.5 | Optional: high-yield facts deck |
Week by week
| Week | Focus | Practice exam |
|---|---|---|
| Week 1 | Cardiovascular | |
| Week 2 | Respiratory, Critical care | |
| Week 3 | GI, Hepatology | |
| Week 4 | Renal / Urinary, Endocrine | |
| Week 5 | Heme / Onc | |
| Week 6 | Immune / ID, Rheumatology | |
| Week 7 | Neurology, Dermatology, Psych / Behavioral, Geriatrics | |
| Week 8 | Weakest areas; Full-length timed simulation: four sessions of up to 60 questions; Rest |
ABIM sells no practice exam; its free tutorial has practice questions. Week 1 and week 8 use a timed qbank simulation of the four-session format.
How to review while working full time
A plan that assumes free evenings fails in the first week of nights. In Sean’s sessions the calendar has two kinds of weeks. On work weeks, studying is maintenance: Anki capped at an hour, 15 questions in about 30 minutes at real ABIM pace, 30 minutes reviewing them and 30 minutes of content, about half a chapter. On lighter weeks it grows to roughly an hour of questions, an hour of review and 30 to 60 minutes of content.
The 15-in-30 pace is not arbitrary. Each exam session holds up to 60 questions in up to two hours (ABIM exam details), about two minutes a question, so practicing at that speed from week one means there is no separate “timing” phase at the end. Before the exam, sit at least one full four-session simulation from your question bank, because the length of the day is its own test. ABIM’s free tutorial (ABIM exam tutorials) is worth running once so the interface holds no surprises.
Board review course, question bank or tutor?
Most residents use some mix of three things, and each solves a different problem:
- A board review course, live or recorded, re-teaches content in blueprint order. It suits people with real content gaps and time to sit through lectures.
- A question bank is where the score is made. It trains the pace and shows your weak areas. Many residents do one bank thoroughly rather than two halfway.
- One-on-one tutoring fixes what neither of those can see: why you keep losing the close calls, and a schedule that survives your rotation calendar.
Our students usually keep their question bank and drop the extra course. Sessions are spent working your missed questions live, building the tie-breaker list, and adjusting the week when a rotation changes. We also set students up with an ABIM Anki deck combined from several community decks, so content review takes minutes a day instead of hours.
Who tutors internal medicine boards here
Two internists on our team tutor ABIM prep. Sean Moazezi, DO, founded The Boards Professor; his ABIM students include residents preparing through the in-training exam. Dr. David Wadie completed an internal medicine residency, became board certified in internal medicine, and is now a cardiology fellow, a natural fit for the 14% of the exam that is cardiovascular. Read more on our ABIM tutoring page.
If the exam is close, or you have already failed
Results come out within three months of the last exam date (ABIM), so a fall result usually leaves time to prepare for the next year’s administration. Board eligibility lasts seven years from completing training (ABIM policies), and most people get there: ABIM reports that 98% of physicians seeking initial certification eventually pass (ABIM pass rates). Start a retake plan from your score report’s content-area results rather than from the top of the blueprint, and put most of the hours where the report and the blueprint weights overlap.
