Bottom line upfront
UWorld is non-negotiable. Complete it once, review incorrects twice. Add Amboss for clinical depth, UpToDate for management, and Sketchy for pharmacology. All four are inside iMD App for $75/year — vs $2,300+ if subscribed individually. The 12-week study plan below is built around these four tools.

1. USMLE Step 2 CK Facts & Scoring 2026
USMLE Step 2 CK tests clinical knowledge and decision-making — applying basic science to real patient scenarios across all major disciplines. It is now the most important licensing exam for residency matching, having overtaken Step 1 in weight since Step 1 became pass/fail in 2022.

What the exam covers
- 318 questions across two test days — 9 blocks of approximately 35-40 questions each
- Internal medicine — the heaviest domain, approximately 30-35% of questions
- Surgery, obstetrics & gynaecology, paediatrics, psychiatry — each 10-15%
- Biostatistics and epidemiology — approximately 5-10% — frequently tested, often overlooked
- Patient safety and ethics — 5-10% — IMGs consistently underperform here
Step 2 CK scores are now the primary filter for residency program screening in 2026. Programs that previously screened on Step 1 now use Step 2 CK as the main academic metric. A score of 240+ is considered competitive for most specialties. IMGs need to treat Step 2 CK with at least the same seriousness as Step 1.

The gold standard. UWorld Step 2 CK contains 3,900+ questions written to mirror the real exam in format, difficulty, and clinical reasoning style. No other QBank comes close for exam simulation.
The UWorld explanations — particularly the clinical pearls, tables, and diagnosis summaries — function as a textbook. Most high scorers complete UWorld twice: once through, then a second pass on incorrects.

Best supplemental QBank. Amboss has 3,441 Step 2 CK questions — harder than UWorld on average, with an “Attending Physician” mode that pushes clinical reasoning beyond exam level. Users who used Amboss scored 10.4 points higher on Step 2 CK than those who did not.
The Amboss Knowledge Library — 2,000+ clinical articles with drug interaction tools, diagnostic algorithms, and clinical images — makes it the best tool for understanding why an answer is correct, not just what is correct.

The clinical bible. UpToDate is the real-world clinical reference used by physicians globally. For Step 2 CK, it is indispensable for understanding management algorithms, treatment thresholds, and guideline-based clinical decision making — the exact type of reasoning Step 2 CK tests.
Look up every clinical topic you get wrong in UWorld or Amboss. UpToDate gives you the full management framework that exam explanations summarise.

Best for pharmacology. Sketchy uses visual mnemonic stories to make drug mechanisms and microorganism characteristics stick permanently. Step 2 CK tests pharmacology heavily — drug mechanisms, side effects, contraindications, and drug interactions appear throughout.
If you retain pharmacology poorly with traditional memorisation, Sketchy is transformative. Most students who use it report retaining drug details 6-12 months later with no review.

Best video lectures. Dr. Jason Ryan’s Boards & Beyond covers USMLE Step 2 CK topics with exceptional clarity, particularly for cardiovascular, respiratory, and renal pathophysiology. Excellent for visual learners who need concepts explained before doing questions.

Most accurate score predictor. NBME shelf exams and self-assessments are written by the same organisation that writes the real USMLE. They are the most accurate predictor of your actual exam score. Do at least 2 NBMEs in your final 4 weeks — one at week 8-9 and one at week 11.

Second most accurate predictor. UWSA1 and UWSA2 closely mirror real exam difficulty. UWSA2 in particular is considered by many students the most accurate single predictor available. Do UWSA1 around week 9, UWSA2 around week 11, and use your score to calibrate final revision.

Subscribing to UWorld ($599) + Amboss ($448) + UpToDate ($600) + Sketchy ($300) + Boards & Beyond ($300) individually costs over $2,247 per year. iMD App includes all five — plus NBME self assessments, UWorld self assessments, and 45,000+ additional resources — for $75/year. That is 97% cheaper.
3. The 12-Week IMG Step 2 CK Study Plan
This plan is built for IMGs with clinical experience targeting 240+. It prioritises UWorld as the primary driver with Amboss as the clinical depth tool. Adjust weekly targets based on your baseline NBME score.
| Week | Focus | Primary resource | Target |
|---|---|---|---|
| Week 1–2 | Baseline assessment + Internal medicine foundation | NBME baseline + UWorld IM | 40 UWorld Qs/day · Read every explanation |
| Week 3–4 | Surgery + OB/GYN | UWorld + Amboss articles | 50 Qs/day · Amboss read-through on incorrects |
| Week 5–6 | Paediatrics + Psychiatry + Ethics | UWorld + Sketchy Pharm | 50 Qs/day · Sketchy 1hr/day for drugs |
| Week 7–8 | Complete UWorld first pass · Mixed systems | UWorld timed blocks | NBME 1 at end of week 8 · Target 240+ |
| Week 9–10 | UWorld incorrects second pass | UWorld + UpToDate deep dives | UWSA1 at week 9 · Focus weak areas |
| Week 11 | Final simulation + weak spot revision | UWSA2 + NBME 2 | Compare scores · Last Amboss reads |
| Week 12 | Light review only · No new material | UWorld incorrects + Sketchy | Sleep, eat well, exam day execution |
Never do UWorld in tutor mode for your main passes. Timed, random blocks simulate the real exam and build the mental stamina that exam day requires. Save tutor mode only for specific topic review when you want to slow down on a weak area.
4. IMG-Specific Strategy for Step 2 CK 2026
IMGs face specific challenges on Step 2 CK that US graduates do not. These three areas consistently trip up IMGs and must be addressed directly in your study plan.
Area 1 — Patient autonomy and ethics
US medical culture places patient autonomy above physician opinion in nearly every ethics scenario. IMGs trained in countries with paternalistic healthcare models often struggle with ethics questions because their clinical instinct conflicts with the correct USMLE answer. The rule is simple: competent adults have the right to refuse any treatment, even life-saving treatment. Do not override this with “but the patient will die.” Practise 200+ ethics questions from UWorld and Amboss specifically.
Area 2 — Epidemiology and biostatistics
Approximately 5-10% of Step 2 CK questions test sensitivity, specificity, PPV, NPV, likelihood ratios, and study design. IMGs frequently skip this domain in favour of clinical questions. Do not. Biostatistics questions are formulaic — if you learn the formulas and the logic once, you get every question right. Use Amboss’s biostatistics module specifically.
Area 3 — US-specific management guidelines
Step 2 CK tests US clinical guidelines, not general international practice. Drug choices, screening intervals, and management thresholds differ from UK, Pakistani, Egyptian, or Indian guidelines. Use UpToDate inside iMD App to verify the US standard for every management question you review. Pay particular attention to cancer screening guidelines, hypertension thresholds, and diabetes management targets — these frequently appear and have US-specific answers.
