USMLE Step 1 has been pass/fail since 2022, which changed the stakes but not the content — the exam still covers the full basic science curriculum, organized by organ system, in a testing session that runs roughly 8 hours across up to 280 questions. The pass/fail shift means the exam is no longer the primary residency-ranking metric it once was, but "pass" still requires genuinely knowing the material, and a failed attempt is a serious setback. The free and low-cost resource ecosystem that has grown up around Step 1 — YouTube video review, the AnKing Anki deck, and UWorld-style question banks — is unusually mature for exactly this reason.
This guide covers how these pieces fit together: which free video content covers Step 1's systems-based curriculum, how the AnKing deck integrates with daily video review rather than replacing it, and a realistic dedicated-study timeline.
What Step 1 Actually Tests
Step 1 questions are built from an integrated content outline organized around organ systems (cardiovascular, respiratory, renal, and so on) rather than the separate pre-clinical courses (biochemistry, physiology, pharmacology, pathology) most medical schools teach them in. This is the single most important structural fact for planning your review: your school's course sequence and Step 1's actual content organization are different shapes, and dedicated Step 1 study time is largely spent re-organizing what you already learned into the systems-based frame the exam actually uses.
Video Review: Systems-Based, Not Course-Based
The dominant paid video resource for Step 1 is Boards and Beyond (Jason Ryan), organized by organ system and widely used alongside UWorld as a primary review pass — most students layer it directly against First Aid, the standard Step 1 review text. While Boards and Beyond itself is subscription-based, its systems-based organizational structure is what most successful free-resource study plans replicate: reviewing your pre-clinical course notes reorganized by organ system, using free YouTube channel content (Ninja Nerd for detailed physiology and pathophysiology walkthroughs, Osmosis for shorter concept-level videos) to fill specific gaps rather than as a full primary review source.
Sketchy-style visual mnemonics (the paid Sketchy Micro, Pharm, and Pathology series) are widely credited by students as the single highest-yield resource for microbiology and pharmacology specifically — subjects with enormous rote-memorization loads that visual mnemonic stories measurably outperform plain repetition for. Free YouTube contains many creator-made visual mnemonic videos inspired by the same principle for students without a Sketchy subscription, though none match Sketchy's production consistency across the full curriculum.
The AnKing Deck: Where Spaced Repetition Fits
The AnKing Step Deck is the most widely used pre-made Anki deck for Step 1 preparation — built and maintained by a team of medical students and residents, covering the full Step 1 content outline, and designed to integrate directly with First Aid and UWorld (many cards reference specific First Aid page numbers and UWorld question IDs). For a full walkthrough of Anki setup, FSRS scheduling, and how the AnKing deck compares to building your own cards from scratch, see Anki vs RemNote vs AI alternatives.
How AnKing fits into a daily schedule: the standard approach is "unsuspend" a manageable number of new AnKing cards per organ system as you cover that system in your video or reading review, then do daily spaced-repetition review of previously unsuspended cards alongside new ones. Most successful dedicated-study plans budget 2-3 hours per day purely for Anki review by the later weeks of preparation, once the card backlog has grown to cover most of the curriculum — this is a real time commitment that needs to be planned for, not squeezed in around other study.
The common mistake: unsuspending the entire AnKing deck (tens of thousands of cards) at once. This creates an unsustainable daily review queue almost immediately. Unsuspend by organ system, matching your pace to whatever systems-based review (video or reading) you are doing in parallel, so your Anki queue and your content review stay synchronized.
Question Bank Practice Is Non-Negotiable
No amount of video review or flashcard volume substitutes for UWorld-style question practice — timed, clinical-vignette-style multiple choice questions with detailed explanations that teach you how Step 1 actually tests a concept, which is often meaningfully different from how a textbook or video presents it. UWorld itself is the dominant paid QBank and is treated by essentially all successful Step 1 candidates as mandatory, not optional, regardless of how thorough their video and flashcard review has been.
The realistic allocation: dedicated Step 1 study time typically splits roughly into content review and Anki review in the earlier weeks, shifting toward majority UWorld question practice (with content review as a targeted response to missed questions, not a separate parallel track) in the final third of the preparation period. Students who spend their entire dedicated period on content review and save all question practice for the final week consistently underperform students who start question practice earlier and use it to direct further review.

A Realistic Dedicated Study Timeline
Most US medical schools allocate 4-8 weeks of dedicated Step 1 study time after pre-clinical coursework ends, though the right length depends heavily on how much of the content is already solid from your coursework.
First half: systems-based content review (video or reading), paired with Anki card unsuspension matched to the system currently being covered, plus lighter UWorld practice as a diagnostic tool to find weak areas early rather than waiting until review is "finished."
Second half: the balance flips — the majority of daily time goes to UWorld questions (typically in timed blocks matching the real exam format), with content review directed specifically at whatever the question review reveals as weak. Anki review continues throughout at whatever volume the daily queue requires; this generally does not shrink, since the deck's spaced-repetition algorithm keeps surfacing cards regardless of how far into dedicated study you are.
Final week: taper question volume, focus on weak-area review and full-length practice exams (NBME self-assessments are the standard, more predictive of actual performance than any third-party resource), and prioritize sleep over additional cramming — the retention benefit of an extra night of sleep before the actual exam outweighs most last-minute content review.
Step 1's free and low-cost resource ecosystem is unusually mature because so many medical students have iterated on the same basic structure: systems-based content review, AnKing's spaced-repetition deck layered on top, and UWorld question practice as the non-negotiable core. None of the three pieces substitutes for the others.
