In short: to build USMLE Step 2 CK practice questions, upload your shelf notes, rotation notes, review book chapters or your own summaries, and the AI writes practice questions with an answer key and explanations in seconds. Step 2 CK is reported as a numeric 3-digit score, and the minimum passing score is 218 as of July 1, 2025. For exams on or after May 7, 2026, the exam runs as sixteen 30-minute blocks of no more than 20 questions each inside one 9-hour session, with at least 55 minutes of break time. Because Step 1 is pass/fail, Step 2 CK is the only scored step programs see, which is why the number on your transcript now does so much work in the Match.

What a Step 2 CK practice question generator does

Test yourself on your own clinical notes, not a QBank you have memorized

Every Step 2 CK candidate hits the same wall. On the second pass through a question bank you stop reasoning through the vignette and start recognizing it. You read two lines, remember that this is the one with the pericardial rub, and click. Your percentage climbs while your clinical reasoning stays exactly where it was. This tool changes the source of the questions. Upload the material you are actually studying, a shelf note set on nephrology, your surgery rotation notes, a review book chapter on antepartum care, and the AI can act as an AI MCQ generator from a PDF and write questions that are new every single time. A miss points straight back at the topic to review, and the next set is one upload away.

Works with any notes or review book

Upload shelf notes, rotation notes, a review book chapter, lecture slides or the summary you wrote after reviewing a QBank block. If the file explains a clinical topic, the generator can build questions on it.

Target one discipline at a time

Weak on OB/GYN or on psych pharmacology? Upload the notes for that discipline alone and drill where your accuracy is soft, instead of grinding mixed blocks that keep testing what you already have cold.

Fresh questions every session

Generate a new set each time so you are testing reasoning, not recall of a specific stem. Repeated retrieval on unseen items is what actually moves a 3-digit score, and it is the one thing a re-used QBank cannot give you.

The shorter blocks are not a cosmetic change, and they should change how you practice. A 40-question hour was a marathon that rewarded pacing discipline over long stretches. Twenty questions in 30 minutes is a sprint, and you now reset sixteen times in a day instead of eight. That means more transitions, more chances to lose or regain rhythm, and less room to bank time on easy items early in a block. Practicing in short, frequent sets of roughly 20 questions mirrors the real day far better than sitting a single 40-question slog. Build the habit of opening a set, reading carefully, moving at a steady clip and closing it out clean. Then take the break. The extra 10 minutes of minimum break time exists precisely because you have more block boundaries to manage, so plan where your food, water and bathroom stops land rather than improvising them on test day.

Simple process

How to make Step 2 CK practice questions in 4 steps

1
Upload your material
Drop in shelf notes, rotation notes, a review book chapter or your own summaries. Scanned and handwritten pages are read with OCR.
2
Set the drill
Pick the question count and difficulty. A 20-question set matches the length of a real block under the current format, so use it to rehearse the actual rhythm.
3
AI writes questions
The AI reads your content and writes clinical vignette style multiple choice questions with an answer key and clear explanations.
4
Review and repeat
Score the set, read the explanation behind every miss, then upload the notes for those topics and generate a tighter drill on just that material.

Why Step 2 CK carries so much weight now

Step 1 became pass/fail in January 2022. From that point, Step 2 CK became the only numerically scored USMLE step a residency program sees on your application. A single 3-digit number, sitting where two used to be. Program directors did not stop wanting a comparable metric just because one disappeared, so the weight shifted onto the score that remained. That is the whole reason Step 2 CK prep feels heavier than it did a few years ago, and why applicants aim far above the 218 minimum rather than at it.

The content is clinical knowledge, with an emphasis on health promotion and disease prevention, diagnosis, and patient management. The disciplines run across Internal Medicine, Surgery, Pediatrics, Obstetrics and Gynecology, and Psychiatry, plus other areas. Vignettes are long. They give you a patient, a history, vitals, sometimes labs or an image, and then ask what you would do next. Recall alone will not carry you. You have to hold the whole picture and make a decision, which is exactly the skill that erodes when you recognize a question instead of working it.

That is where generating questions from your own notes earns its place in a study plan. Your shelf notes are the compressed version of everything you learned on a rotation, in your own language, with your own shorthand. Turning that document into fresh questions forces retrieval on the exact content you decided was worth writing down. Get one wrong and you do not need to hunt for the source. It is right there in the file you uploaded. The loop is short: upload, drill, miss, reread the two paragraphs that explain the miss, generate again. Run that loop on one discipline at a time and the soft spots close faster than they do in a mixed block where every miss sends you somewhere different.

Who uses this to prep for Step 2 CK

Students in their clinical years

Third and fourth year students studying for shelf exams and Step 2 CK at the same time. Upload the notes from the rotation you are on right now and get questions on that material tonight, while it is still fresh and still on the wards with you.

Students who exhausted a QBank

If you have already been through a question bank and your second pass feels like recognition rather than reasoning, upload your review notes and get questions you have never seen. Fresh stems on familiar content is exactly what a stalled score needs.

IMGs and retakers

International medical graduates preparing for the Match and anyone retaking after a score that did not land where they needed it. Rebuild from your own notes on the weak disciplines and drill until the misses stop clustering in one place.

USMLE Step 2 CK practice questions, answered

How many questions are on USMLE Step 2 CK?
The total number of questions on Step 2 CK does not exceed 318. Under the current format, they are split across sixteen blocks of no more than 20 questions each, and every block is 30 minutes long. Exact counts vary slightly between forms. If your notes are handwritten or scanned, run them through an OCR tool like DocuOCR first so the generator can read every page.
What is a passing score for Step 2 CK?
The minimum passing score is 218, effective July 1, 2025, raised from the previous 214. Step 2 CK is reported as a numeric 3-digit score. Since Step 1 became pass/fail in January 2022, Step 2 CK is the only numerically scored USMLE step that residency programs see, so most applicants aim well above the pass line rather than at it.
How long is the Step 2 CK exam?
Step 2 CK is one 9-hour testing session. Under the current format that session holds sixteen 30-minute blocks, a minimum of 55 minutes of break time and a 5-minute optional tutorial. If you skip the tutorial, that time is added to your break pool. The day is long, so build stamina during prep rather than only accuracy.
What changed on Step 2 CK in May 2026?
For exams on or after May 7, 2026, Step 2 CK moved to sixteen 30-minute blocks of no more than 20 questions each, with at least 55 minutes of break time and a 5-minute optional tutorial. The old structure was eight 60-minute blocks of up to 40 questions, 45 minutes of break and a 15-minute tutorial. The 9-hour session and the 318 question ceiling did not change.
Is Step 2 CK harder than Step 1?
It is different rather than strictly harder. Step 1 tests basic science recall and mechanism. Step 2 CK tests clinical knowledge with longer vignettes and asks what you would do next for the patient, with an emphasis on health promotion and disease prevention, diagnosis and management. Because it is now the only scored step, it carries far more weight for the Match.
Can I use my own notes to make Step 2 CK practice questions?
Yes, and that is the point of this tool. Upload your shelf notes, rotation notes, a review book chapter or the summaries you wrote after a QBank block, and the AI writes brand new vignette style questions from that exact material with an answer key and explanations. A miss points straight back at the topic you need to review.
Is this an official USMLE practice test?
No. PDFQuiz is an independent study tool and is not affiliated with or endorsed by the NBME, the FSMB or the USMLE program. It generates practice questions from the material you upload so you can rehearse clinical reasoning, and it does not reproduce real exam questions. Use it alongside official USMLE materials from usmle.org, not as a replacement.
