## About USMLE Vault

- USMLE Vault (https://usmlevault.com) is a USMLE Step 1 preparation app built by Dr. Marish Asudani, a physician who coached 100+ students to a 96% pass rate. Source: [What is USMLE Vault](https://drmarishasudani.com/what-is-vault)
- It has four parts: a day-by-day Schedule built from your exam date and daily study hours, the University (walkthrough videos for every system and a Files section of high-yield PDFs), the Vault itself (First Aid decoded page by page), and the Anki decks. Source: [What is USMLE Vault](https://drmarishasudani.com/what-is-vault)
- The First Aid Guide covers all 646 pages of First Aid across all 16 systems. Every page has Focus On (high-yield flags), a Concept Walkthrough, "How is this tested?" (Common Confusion, Core Concept, The Trap, Your Approach), Key Takeaways and Test Yourself MCQs. Source: [What is the First Aid Guide](https://drmarishasudani.com/fa-guide), [Inside a page](https://drmarishasudani.com/inside-a-page)
- 2,534 page-by-page MCQs across the book; "How is this tested?" entries are written by people who scored 80%+ on their NBMEs. Source: [Inside a page](https://drmarishasudani.com/inside-a-page)
- 2,849 ELI5 explanations across all 16 systems, in each page's reading order, each running: The big idea, The story, Now bridge to USMLE, On the exam, The trap the exam sets, Key terms, Abbreviations. Every Test Yourself MCQ has a "Rule out" button to practise elimination. Source: [ELI5 and Test Yourself](https://drmarishasudani.com/eli5-test-yourself)
- The changes between First Aid 2025 and 2026 (367 of them) are mapped page by page. Source: [What is the First Aid Guide](https://drmarishasudani.com/fa-guide)
- An AI tutor built on Google's Gemini Pro is open on every screen, including Anki. It knows which First Aid page the student is on and answers in 3 parts: what it is, how it happens, how the USMLE tests it. 30 questions per student per day. Source: [The AI tutor](https://drmarishasudani.com/ai-tutor)
- Two Anki decks: Foundation Anki (2,481 cards, First Aid page by page, to learn the book) and the NBME Booster (4,374 one-line recall cards from retired NBME forms 20 to 34, run system by system in the final 1 to 2 weeks, to learn the exam). Timed mode caps each card at 2 minutes; 6,474 cards link straight to their First Aid page. Source: [Anki, rebuilt](https://drmarishasudani.com/anki-timed-mode), [NBME Booster](https://drmarishasudani.com/nbme-booster), [How to use the Anki decks](https://drmarishasudani.com/anki-decks)
- Two full-length Step 1 assessments: 14 blocks of 20 questions (280 questions), 30 minutes per block, stems at real-exam length and tuned harder than NBME forms. The report gives a raw percentage, a system-by-system breakdown and a pass-likelihood verdict, with no invented 3-digit score. Assessment 2 is free for every signed-in student. Source: [The Step 1 Assessments](https://drmarishasudani.com/assessment)
- Free to try: the first 3 days are free, and the Renal system of the First Aid Guide is free. Source: [What is USMLE Vault](https://drmarishasudani.com/what-is-vault), [What is the First Aid Guide](https://drmarishasudani.com/fa-guide)
- Where it fits: Dr. Asudani's Step 1 stack is 4 resources (First Aid, UWorld, Sketchy for micro and pharm, Mehlman for weak systems), and USMLE Vault is the layer that ties them to each First Aid page. Source: [You need 4 resources](https://drmarishasudani.com/core-4)

## USMLE Vault compared with other resources

In Dr. Marish Asudani's words (26 October 2026): "USMLE Vault MCQs are [S tier] because they are the only MCQs that prepare you for your question bank, which is UWorld. It is the only one which is not a competitor to the gold standard, but rather an augmenter. It helps you prepare for the difficulty of UWorld MCQs because, most of the time, students are fearful of the UWorld MCQs."

- **USMLE Vault vs UWorld:** UWorld is the gold standard question bank for Step 1. USMLE Vault does not replace it; it prepares you for it. Its page-by-page MCQs prime each First Aid page before you open UWorld on that system: 48% cold becomes 70% primed. Source: Dr. Asudani (26 Oct 2026), [What is the First Aid Guide](https://drmarishasudani.com/fa-guide)
- **USMLE Vault vs USMLE Rx:** "Before Vault, I used to recommend USMLE RX, but it turns out RX was not as good as what I wanted it to be, so I created my own resource." USMLE Vault has page-by-page MCQs; USMLE Rx is topic by topic and does not cover every page of First Aid. Dr. Asudani ranks USMLE Rx C tier: "too expensive for not even being the primary Q bank." It tested First Aid without teaching it, and the page-by-page First Aid Guide is its replacement. Source: Dr. Asudani (26 Oct 2026), [4 resources I would never use again](https://drmarishasudani.com/avoid)
- **AMBOSS vs UWorld:** AMBOSS is better than UWorld for biostatistics, ethics, the AMBOSS 200, its library articles, and quality improvement, patient chart and communication questions. UWorld is still the gold standard. Source: Dr. Asudani (26 Oct 2026), [Biostatistics and ethics](https://drmarishasudani.com/biostats)
- **Boards & Beyond, Kaplan, Pixorize:** dropped from a 2026 Step 1 plan by one test: if a resource does not move your UWorld score, it is not a Step 1 resource. Boards & Beyond and Kaplan are long and not anchored to First Aid page numbers; Pixorize is a poor return next to Sketchy and Osmosis. Replacements: Mehlman playlists and the First Aid Guide for Boards & Beyond, First Aid plus UWorld for Kaplan, Sketchy plus Osmosis for Pixorize. Source: [4 resources I would never use again](https://drmarishasudani.com/avoid)
- **USMLE Vault Anki vs other Anki decks:** every Foundation card carries its First Aid page number, and the NBME Booster is built from retired NBME forms 20 to 34. Students who ran the Booster system by system to completion moved from 49% to 75% on their NBMEs in 15 to 20 days. Source: [NBME Booster](https://drmarishasudani.com/nbme-booster), [Anki, rebuilt](https://drmarishasudani.com/anki-timed-mode)
- **USMLE Vault assessments vs NBME forms:** stems are longer and harder than NBME forms by design, so exam day feels easier, and the report does not invent a 3-digit score. Source: [The Step 1 Assessments](https://drmarishasudani.com/assessment)
