How every card works
Not just a list of letters. A card that teaches.
A mnemonic only helps if you know what each letter means and why it's true. That's why all 717 cards follow the same five-part pattern.

- 1
The mnemonic
Short and vivid: a classic you may know, or a new StepLobe one built to stick.
- 2
Every letter, decoded
What each letter stands for, with the one detail the exam wants beside it.
- 3
Why it works
The mechanism in two lines, so a forgotten letter can be rebuilt instead of guessed.
- 4
The real picture
A licensed clinical photo or an original diagram whenever seeing it is what makes it stick.
- 5
The exam hook
How an NBME-style stem describes the patient, and what you should think.

New in the 2nd edition
Rebuilt from the first page to the last.
Same promise, much better book: clearer cards, real images and questions to prove you know it.
Rewritten card by card
Each of the 717 cards was checked against current guidelines and nomenclature, and rewritten to teach the mechanism, not just the list.
Real photos replace drawings
161 licensed clinical photographs (rashes, smears, X-rays, CT, histology) and 169 new diagrams drawn for this edition.
Original mnemonics
113 mnemonics borrowed from commercial review books were replaced with new StepLobe ones, and weak ones were made shorter and catchier.
Test yourself
136 exam-style questions with full explanations, plus a rapid-recall sheet at the end of every section.
What's inside
All 17 subjects, in Step 1 order.
Each section opens with a roadmap and closes with 8 exam-style questions and a rapid-recall sheet. Classics like PROVe and FROM JANE sit beside new StepLobe mnemonics.

“Struggling doesn't mean you're failing. It means you're learning something hard.”
I built StepLobe to be the study partner I wished I'd had. Every mnemonic in this book comes with the reason it is true, so you can walk into the exam room calm, ready and proud of what you've built.
