Step 1

Step 1 has been pass/fail since January 2022. The exam tests integrated foundational science across organ systems with heavy emphasis on pathology, pharmacology, and physiology. NBME publishes the Content Outline publicly at usmle.org. Upload your First Aid, Pathoma chapters, Sketchy notes, or your own materials and exclam.ai builds a daily plan around your dedicated period — UWorld and Amboss stay where they live, exclam.ai is the schedule layer.

## Typical Step 1 prep stack

What candidates actually use to prep for Step 1. exclam.ai is the planner layer — UWorld and Amboss stay platform-locked; First Aid, Pathoma, Sketchy notes, and your own materials are what you upload.

First Aid for the USMLE Step 1 (the canonical outline + spaced retrieval anchor)

Pathoma (Dr. Sattar) for pathology — second canonical text

Sketchy Medical for microbiology and pharmacology mnemonics

Boards & Beyond or Dr. Najeeb for video-driven content

UWorld Step 1 QBank (industry standard, ~3,000+ questions)

Amboss QBank + library (subscription-based, integrated with UWorld practice)

NBME practice exams (4–6 available, the closest format match)

## How exclam.ai helps with Step 1

The honest framing: exclam.ai is not a UWorld replacement. UWorld is the QBank and you should keep it. exclam.ai is the daily plan + flashcard + retention layer that wraps UWorld + Amboss + your notes into a coherent schedule against your dedicated period.

### Flashcards from First Aid + Pathoma

Upload your First Aid chapters or Pathoma sections and exclam.ai generates spaced-retrieval flashcards mapped to organ systems.

### Dedicated-period scheduling

A 20-week dedicated plan against your test date, with coverage → review → mocks phases auto-balanced.

### Wraps your UWorld blocks

exclam.ai schedules when to do UWorld blocks, when to review missed items, and when to switch to mock NBME exams. The Qbank stays at UWorld; the schedule lives here.

## Step 1 questions

Step 1 is pass/fail — does the prep approach change?

Less than candidates think. Pass/fail removed the score-chasing pressure but the content breadth and exam fatigue are unchanged. Plan for the same ~600 hours, just without the obsession over 240 vs 250.

Is upload-based prep useful for Step 1?

Not as your primary stack — UWorld and Amboss are platform-locked and uncrackable for a planner workflow. But uploading First Aid, Pathoma chapters, Sketchy notes, or your own organ-system summaries gives exclam.ai a daily plan, weak-area drilling, and FSRS retention that wraps your UWorld use.

When should I take Step 1?

Most US MD candidates take Step 1 at the end of M2 year. DO candidates may take Step 1 + COMLEX Level 1 in the same window. International candidates plan around residency match deadlines.
