Before You Buy: Step 1 in 2026
Two things shape how you should use books for Step 1 now. First, it’s pass/fail, so the goal is solid coverage, not squeezing out extra points. Second, from May 14, 2026, the exam is fourteen 30-minute blocks of up to 20 questions each, still in one 8-hour day, per USMLE.
Books are how you learn and review. Most of your practice should still be timed questions on a computer, from a question bank such as UWorld or AMBOSS, because that’s how the exam is taken. A common setup is First Aid plus Pathoma plus a question bank, with Anki flashcards for retention.
First Aid for the USMLE Step 1 2026
The most widely used Step 1 review book: 1,300+ high-yield facts and mnemonics and 1,000+ color images, updated every year.
First Aid is the book most Step 1 students build their prep around. It condenses the exam into more than 1,300 high-yield facts and mnemonics, organized by basic principles and then organ system, with more than 1,000 color clinical images. It’s written by students who did well on Step 1 and reviewed by faculty, and McGraw Hill publishes a new edition every year. The 2026 edition is the 36th.
It’s a reference, not a teacher. Most students read a section, do question-bank questions on it, then annotate First Aid with what they missed. If the facts don’t stick from reading, pair it with flashcards; our guide to the best Anki decks for Step 1 covers the AnKing deck, which is tagged to First Aid pages.
Buy it if you want one book to anchor your prep. Skip it if you can’t get the current edition; a two-year-old copy is missing updates.
Pathoma: Fundamentals of Pathology
A USMLE prep subscription with over 35 hours of online video content.
Pathoma is Dr. Husain Sattar’s pathology course: a 218-page full-color textbook, more than 300 often-tested images, and more than 35 hours of video lectures that walk through the whole book. Pathology runs through most of Step 1, which is why Pathoma shows up on nearly every student’s resource list.
A free account on Pathoma includes six videos. The Pro account starts at $84.95 and gives you 3, 12 or 21 months of video access, and the textbook ships with it. The book isn’t re-released every year, but basic pathology changes slowly.
Buy it if you learn well from video lectures, or pathology is a weak area. Skip it if you’re using another full pathology video course.
Kaplan USMLE Step 1 Lecture Notes (7-Book Set)
Seven volumes, about 2,000 pages, covering every Step 1 subject. Updated each year by Kaplan’s faculty.
Kaplan’s Lecture Notes are the most complete review on this list: seven volumes and about 2,000 pages covering Pathology, Pharmacology, Physiology, Biochemistry and Medical Genetics, Immunology and Microbiology, Anatomy, and Behavioral Science and Social Sciences. Kaplan’s faculty update the set each year; the 12th edition covers 2025–2026, so check for a newer set before you buy.
They’re the same books used in Kaplan’s Step 1 course. See our Kaplan Step 1 review if you’re weighing the course.
Buy it if you want full explanations, not just facts to memorize. Skip it if you’re short on time; 2,000 pages is a lot in a dedicated study period.
BRS Physiology
A concise, outline-style physiology review with a comprehensive practice exam. Doubles as a review for your physiology course.
Linda Costanzo’s BRS Physiology is the standard short physiology review for Step 1: about 330 pages of outline-style review plus a comprehensive practice exam. The 8th edition (2022) is the current one.
Physiology is where many students lose points on mechanisms such as cardiac pressure-volume loops, renal handling and acid-base, and BRS explains those clearly without textbook length.
Buy it if physiology is a weak spot. Skip it if you’re already covering physiology well through a video course.
Rapid Review Pathology
High-yield pathology in outline form, with 500 USMLE-style questions online and the eBook included.
Rapid Review Pathology was Dr. Edward Goljan’s book for five editions. The 6th edition (2023) was revised by Dr. Anthony Alfrey, his chosen successor. It’s 416 pages of high-yield pathology in outline form, with color images and summary tables. Elsevier includes the eBook and 500 USMLE-style questions online.
It covers much of what Pathoma does, so most students pick one as their main pathology resource and use the other for review.
Buy it if you prefer reading to video for pathology. Skip it if you’re already using Pathoma as your main pathology resource.
Robbins and Cotran Review of Pathology
Get extra Pathology practice with Robbins and Cotran's Review of Pathology, which includes extensive vignette-style questions to reinforce clinical applications and incorporate key patient care and diagnostic strategies.
Robbins and Cotran Review of Pathology is a pathology question book: about 2,000 multiple-choice questions with explanations, written by Edward Klatt and Vinay Kumar to match the Robbins textbooks. It’s the biggest pathology question set you can buy on paper.
The 5th edition is current. Elsevier lists a 6th edition, renamed Robbins, Cotran and Kumar Review of Pathology, for January 2027, so if your exam is in mid-2027 or later, it may be worth waiting.
Buy it if you want more pathology practice questions. Skip it if your exam is after early 2027 and you can wait for the new edition.
Kaplan medEssentials for the USMLE Step 1
Visually mapped basic science concepts that pair perfectly with the Kaplan USMLE Step 1 Lecture Notes Book Set.
medEssentials turns Step 1 concepts into charts, diagrams and summary tables, a visual condensed review across the basic sciences. The 6th edition (2022) is 536 pages.
It pairs well with Kaplan’s Lecture Notes as a faster way to review what you’ve already learned.
Buy it if you’re using Kaplan’s Lecture Notes and want a visual summary. Skip it if you’re using First Aid as your summary book.
USMLE Step 1 Books FAQ
What is the best book for USMLE Step 1?
First Aid for the USMLE Step 1. Most students use it as their main review book, alongside a question bank and Pathoma. Buy the current year’s edition; the 2026 edition is the 36th.
Is Step 1 still scored?
No. Step 1 is pass/fail, so there’s no three-digit score. You still need a solid foundation to pass, and Step 2 CK is scored.
How long is Step 1 now?
It’s one 8-hour day. From May 14, 2026, the exam is fourteen 30-minute blocks of up to 20 questions each, with at least 55 minutes of break time. Before that it was seven 60-minute blocks.
Do I need Pathoma if I have First Aid?
Most students use both. First Aid summarizes pathology; Pathoma teaches it through 35+ hours of video, which makes the First Aid pages easier to remember.
Are books enough to pass Step 1?
Usually not on their own. Most students pair one review book with a question bank and spaced-repetition flashcards. Step 1 is taken on a computer in timed blocks, so timed online practice matters.
