Your wrong answer shows what to teach next.
Picking angiotensin II on a bradykinin question shows exactly which piece you're missing. Your next question teaches that piece.

The problem with random
Nothing connects, so nothing sticks.
Most question banks are random. Cardiology, then renal, then a drug you've never heard of. Your brain never gets the chance to connect anything, so it forgets.
So you make flashcards to stop the forgetting. And now you have 2,000 cards due today.
Five questions, at random
- Cardiology
- Psychiatry
- Renal
- Pharmacology
- Biostatistics
Five questions on NARQB
- Physiology
- The drug
- Mechanism
- Side effect
- The fix
So you do what everyone does.
More questions. Another deck. A second pass.
And your score barely moves. Because more of a broken method gets you more of the same result.
Program directors don't see how hard you worked. They see one number.
With Step 1 pass/fail, that number is your Step 2 CK score. It decides whether you choose your specialty, or take whatever is left.
Competitive Edge
Match into the most competitive residency programs & fellowships.
While most students still use traditional random-style question banks, you will have a competitive edge by using the NARQB Method.
High honors in your Clerkship
Set NARQB to focus on your current clerkship. Realistic clinical vignettes will prepare you for any patient you encounter.
Learn without even taking notes
With our built in spaced repetition engine, long term memory is built into your practice. Your only job is to understand the material, not take notes.
Just do 10 questions a day
Consistency is key, and NARQB makes it easy. Just do 10 questions a day and you'll be well on your way to matching into the most competitive residency programs & fellowships.
Your second exam is even easier
Based on how you perform in your first QBank, your next exam will be hyper-focussed on what you missed or struggled with. You are not starting from scratch.
The method
A curated path that adapts as you go. Feels effortless, like reading your favorite story.
Working through a question bank should feel like building a coherent knowledge structure — not memorizing random, disconnected facts.
Concepts build on what you’ve seen
Questions arrive in an order where each new concept connects to ones you’ve already covered — a coherent structure, not disjointed chunks.
Mistakes reshape your path
Get a question wrong and variations on the same objective return on a spaced-repetition schedule until it sticks.
Concepts build on what you've seen
Get it right, and it takes you deeper.
Get a question right, and the next one isn't random. It's the next layer of the same idea. The physiology. Then the drug. Then the mechanism. Then the side effect. Then the fix.
Five questions deep, until the whole idea clicks.
That's how a 270 scorer thinks. Now it's how you practice.
- 1
Physiology
What does ACE do in the renin–angiotensin system?
- 2
The drug
Why start lisinopril in a hypertensive patient with diabetes?
- 3
Mechanism
With ACE inhibited, which vasodilator accumulates?
- 4
Side effect
Two weeks in, a persistent dry cough. What is responsible?
- 5
The fix
The cough persists. Which drug class replaces it?
Mistakes reshape your path
Miss it, and it comes back rewritten.
Same learning objective. One detail changed, and now the answer is different. It keeps coming back until you've beaten every version.
That's how examiners set their traps. Now it's how you train.
Monday · You chose A
A 58-year-old man started lisinopril two weeks ago. He now has a persistent dry cough. Which substance is responsible?
Angiotensin II
Decreased aldosterone
Tuesday · Same objective, one detail changed
A 58-year-old man started lisinopril two weeks ago. His potassium is now 5.9 mEq/L. Which change is responsible?
Angiotensin II
Bradykinin

Spaced repetition is built into the questions. On test day, you've already seen the trick. No flashcards. No notes.
The whole exam, in the right order
Every topic. Highest-yield first. No wasted questions.
The highest-yield material comes first. Then every new chain starts as far as possible from anything you've already seen, so every hour you put in buys new ground instead of repeat ground.
Your exam coverage map in the app fills in the same way, one square for every 1% of the exam.
Order in which one student's exam is covered
- Highest-yield
- Start of a new chain
- Chain continues
It adapts to you
Your next question is picked from your own answers.
NARQB keeps a record of every question you answer: what you got right, what you got wrong, and which wrong answer you chose. It uses that record to pick your next question, so your time goes to the exact things you don't know yet, not to re-doing what you've already mastered.
The more you use it, the better it knows you.
Every session teaches it more about you: the traps that catch you, the topics you already own, and the ones you keep avoiding. The longer you use it, the more precisely it targets what you need.
It keeps getting smarter.
We track which question orders help students perform best, and keep improving the order for everyone. The bank you use a month from now will be better than the one you start with tonight.
Compounded Learning
After this exam, your next one is dramatically easier.
As you progress from STEP 1 to STEP 3, you'll find that the material you struggled with in the previous exam is prioritized first in the next question bank. If there were any concepts you didn't finish, they will also be prioritized in the next question bank. Your learning compounds instead of starting over. You will be glad you started early.
On top of that
You're never studying alone.
Everything around the questions is built from the questions you've done, so it all gets better the more you use it.
A tutor that speaks the exam
It's not a general chatbot. It answers at the level of the USMLE, and it cites the exact questions you've already worked through, so every explanation pulls you back to something you've seen and builds on it.
The more questions you do, the more it has to draw on.
Aldosterone explains the potassium, not the cough. ACE also breaks down bradykinin, which builds up in the airway. You saw the same mechanism in the angioedema case last week.
Question 214, where you chose A
A study guide that writes itself
Everything you struggle with lands in your study guide. It doesn't just name a disease to reread. It shows the progression of ideas inside each topic, where yours broke down, and the exact question and answer choice that tripped you.
Take it straight back to your books.
Cardiology › ACE inhibitors
- 1. ACE converts angiotensin I to angiotensin II.
- 2. ACE also breaks down bradykinin.
- 3. Bradykinin buildup causes dry cough and angioedema.
You chose “Angiotensin II” on Question 214.
Written by experts. Never by a machine.
Every question is written deliberately by experts, from past exams, high-yield resources and the textbooks you trust. Not an infinite AI question factory.
It teaches from first principles, in layers, and shows you exactly how examiners try to make you ignore what you know.
- Past exams
- High-yield resources
- Standard textbooks
- First principles
