If I had 7 days left before the Internal Medicine shelf, I would stop trying to “cover everything” and instead focus on what actually shows up. The IM shelf is not about obscure zebras. It is about pattern recognition, algorithms, and management decisions. Here’s exactly how I would structure my final week.

The Rule: Depth > Breadth. You don’t need 200 topics. You need mastery of the 30–40 that are tested repeatedly.

Day 1 – Cardiology (Highest Yield Topic)

• ACS (STEMI vs NSTEMI vs unstable angina).

• Heart failure (HFrEF meds + acute decompensation).

• Arrhythmias (Afib, AV blocks, VT vs SVT).

• Valvular disease + surgical indications.

• Cardiomyopathies.

Non-negotiables:

• When to cardiovert.

• When to anticoagulate

• When to operate.

• Which heart failure meds improve mortality.

Day 2 – Pulmonary

• PE (Wells → D-dimer → CT).

• COPD vs asthma (DLCO trick).

• Pneumonia management.

• Pleural effusions (Light’s criteria).

• ILD pattern recognition.

If you see hypoxia + normal CXR → think PE.

If DLCO is low → think emphysema or ILD.

Day 3 – Nephrology + Electrolytes

These are thinking questions.

• AKI (pre-renal vs ATN vs post-renal).

• Hyponatremia algorithm.

• Hypernatremia.

• Acid–base disorders (including delta gap).

• Nephritic vs nephrotic.

Electrolytes are free points if you practice the algorithm.

Day 4 – Hematology / Oncology

Focus on differentiation.

• TTP vs HUS vs DIC vs ITP.

• Anemia patterns.

• Leukemias (ALL, AML, CLL, CML).

• Plasma cell disorders (MM vs MGUS vs Waldenström).

• Hypercoagulable states.

Know when to give plasma exchange (TTP).

Know when prolonged PTT actually means clotting (APS).

Day 5 – Infectious Disease

• Infective endocarditis.

• Pneumonia organisms.

• HIV opportunistic infections.

• Viral hepatitis serologies.

Don’t memorize everything. Memorize associations.

Day 6 – Endocrine + Rheumatology

High-yield endocrine topics:

• Thyroid disorders.

• Thyroid nodules algorithm.

• DKA vs HHS.

• Adrenal insufficiency.

• Cushing’s.

Rheum:

• Vasculitis (ANCA vs immune complex).

• SLE.

• Myopathies.

These questions are often lab-heavy and algorithm-based.

Day 7 – Pure Review & Weakness Audit

Re-do missed UWorld questions and go over practice NBME’s one more time.

Rapidly review:

• Murmurs

• EKG basics

• Acid–base

• Antibiotic choices

Review management decisions, not pathophysiology. The last day is not for learning new topics; It’s for tightening mistakes.

How I’d Actually Study Each Day:

• 40–60 UWorld questions.

• Deep review of explanations.

• Make 5–10 rapid recall notes.

• End the night with one algorithm review.
