Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

STEP 2 CK DEDICATED - WEEKS 1-2 REPAIR ARCHITECTURE

YEAR 3 | PAGE 67B - MIXED RECOGNITION -> TARGETED REPAIR -> MANAGEMENT / PREVENTION -> DELAYED TRANSFER

REPAIR RULE: KEEP MIXED QUESTIONS IN THE DAY SO THE EXAM STILL FEELS UNSORTED. USE TARGETED REVIEW ONLY TO REPAIR A DEFINED GAP, THEN RETURN THAT CONCEPT TO FRESH MIXED QUESTIONS. THE GOAL IS NOT TO BECOME GOOD AT TARGETED SETS; IT IS TO MAKE TARGETED REPAIR DISAPPEAR INTO MIXED TRANSFER. C. WEEKS 1-2 - A REPEATABLE DAY

LaneTypical operationEvidence of completion
Mixed timed block(s)Fresh, mixed questions under realistic timing; mark wrongs, guesses and slow corrects.You can identify the physician task, decisive clue and management sequence without topic cues.
Deep reviewReconstruct why the chosen answer failed and why the strongest distractor fails.One reusable rule or algorithm can be stated from memory; no explanation copied verbatim.
Targeted repair Longitudinal lanesOne system/clerkship/task bottleneck: focused questions, short content repair or algorithm drill. Management algorithms + prevention/screening/vaccines + ethics/safety + medication adverse effects.The named gap is narrower after repair and is scheduled for delayed mixed confirmation. Short daily retrieval prevents cross-cutting domains from being postponed to the final week.
End-of-day retrievalBlank-page / oral recall of 3-5 repaired rules; schedule retests.Tomorrow begins with fewer unresolved recurring errors, not a larger note pile.

D. ERROR -> REPAIR TOOL

Error patternBest repairDelayed proof
Knowledge/mechanism gap Next-best-step / sequence errorBrief structured content + causal reconstruction Write the pathway with branch points and contraindicationsNew focused item, then mixed item several days later. Fresh vignette requiring a different point in the same pathway.
Diagnosis vs testing confusion Long-stem / representation errorDefine what is already established vs what test changes management Compress stem into one-line problem representation before optionsMixed questions that alternate diagnosis, test and treatment asks. Timed chart/tabular or dense vignette with accurate lead-in identification.
Timing / rumination Fragile correctTimed half-blocks, commit/move threshold, changed-answer audit Explain why answer is right and why best distractor is wrong without notesStable completion with fewer avoidable reversals / rushed final items. New mixed item solved with reproducible reasoning.

D. ERROR -> REPAIR TOOL — 4. Mixed practice proves transfer; targeted practice repairs a known gap DEEP EXPLANATION Targeted blocks reduce search space and are efficient for rebuilding a weak system or task. Mixed blocks restore the actual exam demand: identify the disease, physician task and

management branch without being told the category first. Dedicated should progressively move from repair toward mixed transfer.

D. ERROR -> REPAIR TOOL — WHY STUDENTS MISS IT Targeted scores often rise quickly, which can look like mastery even when the same concept is missed once topic cues disappear. EASIEST CLUE Use targeted to fix; mixed to prove. 5. Review time is productive only when it extracts reusable reasoning DEEP EXPLANATION A question review should produce a decision rule, a discriminating clue, a corrected management sequence or a new threshold. Merely reading every explanation from top to bottom

can consume hours without changing future decisions.

WHY STUDENTS MISS IT Learners often equate long review time with diligence and feel guilty skipping paragraphs that do not address the error that actually occurred. EASIEST CLUE Ask: what will I do differently on the next case? If the answer is unclear, review is unfinished. 6. Management, prevention, ethics and safety need longitudinal exposure throughout dedicated DEEP EXPLANATION These domains cross organ systems and often depend on sequence, eligibility, contraindications or professional duties. Short daily retrieval creates spacing and prevents the final

week from becoming an impossible catch-up period.

WHY STUDENTS MISS IT Because these topics are distributed rather than belonging to one clerkship, students postpone them while focusing on larger organ-system blocks. EASIEST CLUE Create a small daily lane for screening/vaccines, safety/ethics, emergency algorithms and common medication harms.
