USMLE Step 2 CK Study Plan

A Step 2 CK study plan has to answer three questions: how many weeks you have before your test date, how many hours a day your rotations leave you, and how far your practice scores sit from the 218 passing standard (USMLE scoring). Everything else on this page, from the sample six-week schedule to the rotation version, follows from those three numbers.

The Boards Professor builds these plans one-on-one by live video (Zoom or Google Meet). Our lead tutor, Dr. Shauhin “Sean” Moazezi, DO, is a board-certified internist, and most Step 2 CK students we see are planning around clerkships.

Know the exam you are planning for

From May 7, 2026, Step 2 CK is sixteen 30-minute blocks in one 9-hour day, each with no more than 20 questions, plus at least 55 minutes of breaks (USMLE Step 2 CK). Students who tested earlier sat eight 60-minute blocks, so older study guides and calendars may describe a format you will not see.

Two consequences for planning: time your question-bank work in 20-question, 30-minute sets, and rehearse at least one full day so you know what hour seven feels like. For breaks, score timing and retakes in one place, see the Step 2 CK length, timing and scoring guide.

Build your plan in five steps

1. Count the weeks. Start from your test date and work backwards. If you are still on clerkships, count dedicated weeks and rotation weeks separately.
2. Get a baseline score. A CCSSA form gives you a number on the Step 2 CK scale and a pass probability (NBME CCSSA). Note your question-bank average next to it.
3. Find the gap by subject. Use your shelf scores and the CCSSA breakdown together. A low surgery shelf and a weak surgery section on the CCSSA mean the same thing.
4. Protect the hours. Write down the hours each week your rotations really leave free, then plan for those, not the ones you hope for.
5. Re-test on a schedule. Put the next scored form in the calendar now. The plan changes when the scores do.

Sample 6-week dedicated Step 2 CK schedule

Sample schedule

Sample schedule for illustration only. Not a real student, not real data. Your tutor builds your actual plan around your practice-exam results and the time you have.

Sample 6-week dedicated Step 2 CK schedule: 6 weeks, about 10 hours a day, 6 days a week. One full day off each week.

A typical day

Block	Hours	What
Question bank	5	Two to three timed blocks (20 questions / 30 minutes from May 7, 2026), full review
Anki review	1	Due reviews
Content review	3	Management steps and next-best-step algorithms for missed topics
Other	1	Tutor session

The week Sean sets with his students

In a dedicated period, the week Dr. Moazezi builds with Step 2 CK students looks like this. The numbers move with your date and scores; the structure does not.

• 80 to 100 questions a day, done in timed blocks before any reading.
• Same-day review of every miss, sorted into content gap or test-taking error, with one note on what to do differently next time.
• Misses turned into something you will see again: an Anki card, or a line on a running misconceptions list grouped by organ system.
• A capped Anki load, so flashcards never push out question time.
• A scored practice exam every one to two weeks, reviewed the same day. NBME sells seven CCSSA forms (NBME); see NBME practice exams for how they differ.
• Two or three sessions a week, with a question a day you can text between sessions.

Studying during rotations or work

Most CK preparation happens on the wards. When a rotation takes the day, Sean shrinks the plan instead of pausing it: “the questions say 30 questions a day, half random and half focused on the systems that you’re struggling with the most.”

• Thirty questions on a working day, rising toward 60 when the rotation is light.
• A scored form every week once you are within two months of the exam, even if it feels early. His advice to a student who wanted to wait: “Once a week is the move.”
• One session a week to go over the concepts that week’s misses point to.

Stretching the plan to 12 weeks during rotations

Not everyone gets six free weeks. If your dedicated period is short, or you are studying on rotations, run the same plan at half speed: take the sample six weeks above and give each week’s systems two weeks instead of one. That is the shape of most rotation-friendly 12-week plans.

• Weekdays on service: the 30-question day above, half random and half on the systems of the current two-week block, with misses reviewed that night.
• Days off: two to three timed blocks of 20 questions in 30 minutes, the format of exams from May 7, 2026 (USMLE Step 2 CK).
• Practice tests: one scored form every week or two, moving to the full-day pace of the sample’s last weeks once you reach the final month.

Twelve weeks is a stretch of the same plan, not a different one. If your scores are not climbing by the halfway point, change the split between questions and content, not the length.

From shelf exams to Step 2 CK

Your clerkship shelf exams are Step 2 CK in pieces. Each NBME clinical subject exam is 110 questions on one discipline (NBME timing chart), written in the same style, so a good shelf year is the best start a CK plan can have. Use it on purpose:

• Keep every shelf miss. The missed-concept list you build for medicine, surgery, pediatrics and the rest becomes the first week of your CK review.
• Line up the weak shelves. A low pediatrics or OB/GYN shelf maps straight onto week 4 of the sample schedule.
• Mix the subjects. Shelves test one field at a time; CK mixes them. Switch your question blocks to random mode in the last month of clerkships.
• Book CK while it is fresh. The months right after your core clerkships are when that knowledge is closest to hand.

For each shelf, see our shelf exam tutoring pages.

Where Anki fits

For CK, Anki is a support act. Management steps and next-best-step reasoning come from questions, not cards, so we keep the deck small: cards made from your own misses plus the facts you keep forgetting, on a spaced-repetition schedule that takes minutes, not hours. See the best Anki decks for USMLE if you are choosing one.

What to bring to a schedule session

• Your Step 2 CK test date, or the window your school allows
• Your rotation calendar for the months before it
• Your shelf exam scores
• Any CCSSA or UWorld self-assessment results
• Your question-bank percentage so far

Exam day and Step 2 CK scores

Build the last week around the day itself: sixteen 30-minute blocks, at least 55 minutes of break time and a 5-minute optional tutorial (USMLE). Decide in advance where your longer breaks go.

Scores typically arrive within four weeks, but USMLE says to allow at least eight (USMLE results). If ERAS or a school deadline depends on your score, count back eight weeks from it before you lock the date. In 2024-25, 98% of first-time takers from US MD schools passed (USMLE performance data); what to aim for above 218 depends on your specialty, covered in what is a good Step 2 CK score.

Attempt limits to know before you pick a date

A failed attempt costs more than a delay. USMLE allows no more than three attempts at a Step in 12 months, a fourth only 12 months after the first and six after the latest, and four attempts without a pass ends eligibility for every Step (2026 Bulletin). Once you pass, you cannot retake CK to raise the score, except to meet a licensing time limit. If your last two scored forms are not clearly above passing range, moving the date is usually the cheaper choice. Our attempt-limit guide compares USMLE with COMLEX.
