Best Step 1 Resources 2025: Ranked and Reviewed

There is no shortage of Step 1 resources. There is a shortage of honest advice about which ones are actually worth your time and money. This is that advice — based on personal experience, not sponsorship.

Tier S: Non-Negotiable Core Resources

S Tier
UWorld Step 1 Qbank
Question Bank · ~$300 for 3 months

The single most important Step 1 resource available. UWorld questions are harder than the actual exam, written at a level that forces mechanistic thinking, and the explanations are medical education in themselves. One pass through UWorld in tutor mode teaches you more than any textbook. A second pass in timed mode tells you if it stuck.

Strengths
  • Explanations are genuinely educational
  • Difficulty above real exam level
  • Excellent analytics on weak areas
  • Marks are highly predictive
Weaknesses
  • Expensive for what it is
  • Interface can feel clunky
  • Explanations assume knowledge
Verdict: Do not sit Step 1 without completing at least one UWorld pass. This is the closest thing to a requirement in Step 1 prep.
S Tier
Pathoma
Video Lectures + Book · ~$100

Dr. Husain Sattar's pathology video series is one of the greatest teaching resources in medical education. He explains pathophysiology in a way that makes mechanisms unforgettable. Watch each chapter twice: once for comprehension, once for active recall with frequent pauses. The companion book is equally good for review.

Strengths
  • Sattar explains WHY, not just WHAT
  • Concise — no filler content
  • Book + video complement each other
  • Best pathology resource period
Weaknesses
  • Pathology only (not all systems)
  • Production quality is dated
Verdict: Essential. Especially for pathology-heavy topics like cardiovascular, respiratory, and neoplasia. Start here before First Aid for any organ system.
S Tier
Anki (Zanki / AnKing Deck)
Spaced Repetition Software · Free (decks free)

Anki is not a resource — it's a memory system. The AnKing deck (evolved from Zanki) is the community-maintained flashcard deck that integrates with Sketchy, Pathoma, and First Aid. Done correctly, 200+ cards per day from Week 1 ensures you retain what you're learning. Done incorrectly, it consumes your day without building understanding.

Strengths
  • Scientifically proven retention
  • Free and community-maintained
  • Works on mobile during downtime
  • Long-term retention for clinical years
Weaknesses
  • Easy to use passively (wrong)
  • Review burden grows daily
  • Deck quality varies by tag
Verdict: Essential but requires discipline. The students who benefit most add cards AFTER understanding concepts, not as a substitute for understanding them.

Tier A: High-Value Supporting Resources

A Tier
Sketchy
Visual Mnemonic Videos · ~$200/year

Sketchy uses elaborately illustrated scenes to encode microbiology and pharmacology facts into long-term memory through story-based mnemonics. The science is legitimate — visual-associative encoding produces dramatically higher retention than rote memorization for dense, factual material. Micro and pharm together are roughly 20% of Step 1.

Strengths
  • Retention dramatically higher
  • Micro and pharm are dense — this works
  • Stories are genuinely memorable
Weaknesses
  • Expensive subscription
  • Some mnemonics are a stretch
  • Doesn't teach mechanisms, just facts
Verdict: Highly recommended for micro and pharm specifically. The price is justified if you use it for those two sections consistently.
A Tier
First Aid for USMLE Step 1
Review Book · ~$60

First Aid is the universal Step 1 reference — essentially every medical student uses it. The critical insight: First Aid is not a teaching resource. It's a reference and a consolidation tool. Students who read it linearly rarely benefit. Students who use it as a companion to Pathoma and Sketchy — reinforcing concepts they've already learned — get enormous value from it.

Strengths
  • Universal reference for all topics
  • Updated annually
  • Good for rapid review
  • Annotating it is itself educational
Weaknesses
  • Dense and dry — poor for learning
  • Some outdated material annually
  • Cannot replace video-based learning
Verdict: Essential reference, poor primary resource. Use it to annotate and consolidate, not to learn for the first time.

Tier B: Situationally Useful

B Tier
Amboss
Question Bank + Knowledge Library · ~$200

Amboss is a strong second question bank with a built-in clinical knowledge library. The questions are well-written and the integrated library is genuinely useful. However, for dedicated Step 1 prep, most students get more from completing UWorld twice than splitting time between UWorld and Amboss. Best used as supplementary questions in weak areas or for the library feature.

Verdict: Valuable if you've exhausted UWorld or want additional questions in specific weak areas. Not a UWorld replacement for most students.
B Tier
Boards and Beyond
Video Lectures · ~$150

Boards and Beyond covers physiology and biochemistry particularly well — better than Pathoma for those subjects. If Pathoma isn't clicking for physiology, substitute B&B. Many students use both: Pathoma for pathology, B&B for physiology and biochemistry.

Verdict: Excellent for physiology and biochemistry. Use it to fill gaps Pathoma doesn't cover or when Pathoma's explanations aren't sufficient.

Tier C: Save Your Money

C Tier
Kaplan Step 1 (Videos and Books)
Video Lectures + Books

Kaplan's Step 1 materials are comprehensive but outdated in feel and less yield than the alternatives. The books are dense, the videos are long, and they don't teach reasoning as effectively as Pathoma or B&B. Most high-scoring students do not use Kaplan as a primary resource. If your school provides it for free, use it selectively — it's not worth paying for when Pathoma exists.

Verdict: Use it free if available. Do not pay for it when Pathoma and B&B are superior alternatives at similar or lower price points.

The Optimal Step 1 Resource Stack

If you had to choose exactly what to buy, here's the optimal stack at three budget levels:

BudgetCoreSupplementary
Budget (~$200)UWorld + Anki (free decks)First Aid (buy used)
Standard (~$450)UWorld + Pathoma + Anki + First AidFree 120 (free)
Full (~$650)UWorld + Pathoma + Sketchy + Anki + First AidNBME exams + Amboss library
The #1 resource mistake students make is buying everything and using nothing effectively. Five resources used deeply beats fifteen resources used superficially every time. Pick your stack, commit to it, and don't change it mid-preparation.
