There is no single best ABEM resource; there is a best next resource for your profile, your budget and the weeks you have left. This article is a decision tree, not a ranking. It starts from a measured baseline, segments candidates by need, and maps the emergency-medicine resources to the one job each does well. It also opens with a coverage note, because — unlike internal medicine or family medicine — not every famous board brand actually covers emergency medicine.
A coverage note before you choose
Do not assume a brand you trust for another specialty has an EM product. As of 19 July 2026, UWorld offers ABIM and ABFM board banks but no dedicated emergency-medicine board bank, so it is not part of the ABEM field however good its other banks are; verify before relying on it. The picture around the NEJM Knowledge+ name has also changed: the legacy NEJM Knowledge+ line historically covered internal medicine, family medicine and paediatrics but had no emergency-medicine product. Following AMBOSS's acquisition of Knowledge+, AMBOSS Knowledge+ now offers an ABEM Emergency Medicine board review (more than 2,000 questions, vendor-reported). If you are working from older advice that says "NEJM Knowledge+ has no EM bank," that was true of the legacy line but is now out of date. In practice the EM field is mainly Rosh Review, ACEP PEER, TrueLearn, AMBOSS Knowledge+, and video review such as Hippo Education.
Start with a baseline, not a bank
Sit one short, timed block of unseen questions and read the result as an EM Model domain profile — which of the twenty domains are thin, how you handle high-acuity items, and how you perform under time. That profile decides your branch. A free iatroX baseline is one way to generate it. Throughout, remember that a question-bank percentage is not your exam score; it is a coverage map and a trend line.
The exam you are preparing for
The Qualifying Examination is approximately 305 single-best-answer multiple-choice questions, computer-based at Pearson VUE, built on the Model of the Clinical Practice of Emergency Medicine — 20 clinical domains with an acuity distribution of roughly 30% critical, 40% emergent and 21% lower acuity, at least 8% paediatric and at least 6% geriatric content, and pictorial or image items throughout. Passing it leads to the Oral Certifying Examination. The implication for resource choice is direct: a bank must cover the acuity spread and the images, not merely organ systems.
Segment yourself honestly
- First attempt, on-time — needs breadth across all 20 domains and the acuity spread; benefits from one high-volume bank plus measurement.
- Retake — often knows the content but loses time or misreads high-acuity stems; needs timed, acuity-weighted practice.
- Practising emergency physician — broad shop-floor judgement but rusty on exam-style discrimination and low-frequency topics.
- Weak foundations — needs teaching or video first, then the largest retrieval block.
- Strong knowledge, poor pacing — needs timed volume, not more content.
- Strong on MCQs, weak on applied performance — recognises facts but struggles with resuscitation prioritisation and image reads under time.
The minimum viable ABEM stack
One primary EM question bank done thoroughly; official calibration (the EM Model and your own In-Training Examination history, which is the most honest signal you already own); one teaching or video source only where a domain genuinely needs it; and one modality tool — usually image or ultrasound practice — where that is a specific weakness. Two overlapping banks bought at once is duplicated practice, not insurance.

Budget and time bands
- Free or low-cost — the EM Model, your ITE history for calibration, an iatroX baseline, and one economical bank. Viable for a strong retaker.
- One premium resource — a single primary bank (Rosh, PEER or TrueLearn) plus measurement. The right band for most first-timers.
- Comprehensive — video teaching plus a primary bank plus image or ultrasound practice plus measurement, only where the weeks allow.
- Under four weeks — one bank, timed and acuity-weighted, and the EM Model; omit video and any second bank.
- Four to twelve weeks — one bank thoroughly, plus weekly unseen measurement; add video only for domains you keep missing.
- More than twelve weeks — you can add teaching for breadth, but still anchor on one bank plus measurement.
Decision matrix
| If this is true of you | Follow this branch |
|---|---|
| First attempt, 8–12 weeks | One primary EM bank plus weekly unseen measurement |
| Retake, weak pacing | Timed, acuity-weighted blocks; drop new teaching |
| Practising physician, exam-rusty | One bank for discrimination plus targeted low-frequency reading |
| Weak foundations, long runway | Video teaching first, then the largest retrieval block |
| Image or resuscitation weakness | Add image and ultrasound practice; weight blocks to critical and emergent items |
| Under four weeks to exam | One bank, timed acuity-weighted only, EM Model for calibration |
Three worked profiles
Profile A — first-time resident, twelve weeks. Rosh Review or ACEP PEER as the primary bank, the EM Model and last ITE as calibration, and a weekly iatroX unseen block. Weekly allocation: about 300 questions in mixed mode weighted to the acuity distribution, full review of every miss, and Sunday's unseen block for the trend. Exit criterion: unseen accuracy rising to a stable adequate band with all 20 domains covered before the final fortnight.
Profile B — retaker, weak pacing, eight weeks. Timed, session-paced blocks from a bank not exhausted last time, plus twice-weekly iatroX unseen blocks to confirm speed is improving without accuracy falling. Exit criterion: acuity-weighted blocks completed within time at stable accuracy for two consecutive weeks.
Profile C — strong knowledge, weak images and resuscitation. Add a dedicated image and ultrasound set, weight practice to critical and emergent items, and drill pictorial stems cold. Exit criterion: image-item accuracy reaches parity with your text-item accuracy on unseen blocks.
Evidence hierarchy
Official material first for format (the EM Model and your ITE); primary emergency-medicine guidance for content; vendor pages for product facts, labelled vendor-reported; and your own timed trial for user experience. Treat ranking listicles with caution, especially any that still claim a bank covers EM when the vendor's own page does not.

Bottom line
There is no universal best ABEM resource — only the right next one for your profile, your weeks and your budget, preceded by a coverage check that matters more here than in most specialties. Confirm that a bank actually covers emergency medicine before you rely on it, start from a measured baseline against the twenty EM Model domains and the acuity spread, keep to the minimum viable stack, and let unseen, timed, acuity-weighted performance — not a brand's reputation in another specialty — decide when to continue, supplement, switch or stop.
Frequently asked questions
How do I know whether I have covered the full ABEM blueprint? Map your practice against the 20 EM Model domains and the acuity distribution, not against a raw question total. Build a coverage matrix: list each domain, record unseen accuracy and items done, and check that critical and emergent items — and the paediatric and geriatric minimums — are all represented. Coverage means no domain and no acuity band is a blind spot; finishing a bank is not the same thing.
Can one question bank be enough for ABEM? Yes, if it genuinely spans the acuity distribution, includes pictorial items, and meets the paediatric and geriatric minimums, and if you work it thoroughly. A second bank is justified only when the first leaves a measurable gap — thin image content, or a shortage of unseen items late on. If you add one, use the two-Q-bank rule so it supplies unseen measurement, not duplicate practice.
What should I measure instead of my overall Q-bank percentage for ABEM? Measure domain coverage across the EM Model, your accuracy within each acuity band, your accuracy specifically on image and pictorial items, and your pace under timed conditions. A single percentage hides all four, and — as the percentage article explains — a score built on questions you have already seen tells you little about unseen performance under exam pressure.
When should I stop doing new ABEM questions? Stop introducing new items when your unseen, timed accuracy has plateaued at an adequate band and every domain and acuity band is covered, usually in the last one to two weeks. Redirect that time to reviewing logged errors, drilling any weak image items, and — because the Qualifying Examination leads to it — beginning structured preparation for the Oral Certifying Examination.
Which ABEM resource should I use for my weakest component? Match the tool to the weakness. Weak image or ultrasound reads call for a dedicated image set; weak resuscitation prioritisation calls for acuity-weighted timed blocks; a knowledge gap in a specific domain calls for targeted reading or video; and slow pacing calls for session-paced timed practice. Identify the component from your baseline first, then pick the resource that trains precisely that.
