- Pulmonary diseases (e.g., pneumonia, pulmonary embolism, COPD, asthma)
- Endocrine disorders (e.g., diabetes, thyroid disorders, adrenal insufficiency)
- Gastrointestinal disorders (e.g., hepatitis, inflammatory bowel disease, cirrhosis)
- Renal and electrolyte disorders (e.g., acute kidney injury, chronic kidney disease, hyponatremia)
2. Surgery
- Trauma assessment and management (e.g., ATLS protocols, hemorrhagic shock)
- Preoperative and postoperative care
- Acute abdominal pain (e.g., appendicitis, cholecystitis, bowel obstruction)
- Wound healing and surgical infections
- Common surgical procedures and their indications
3. Pediatrics
- Neonatal conditions (e.g., respiratory distress syndrome, neonatal sepsis, jaundice)
- Congenital heart diseases (e.g., tetralogy of Fallot, transposition of great arteries)
- Pediatric infectious diseases (e.g., measles, mumps, rubella, Kawasaki disease)
- Growth and developmental milestones
4. Obstetrics and Gynecology
- Normal pregnancy and prenatal care
- Complications of pregnancy (e.g., preeclampsia, gestational diabetes, ectopic pregnancy)

- Postpartum complications (e.g., postpartum hemorrhage, infections)
5. Psychiatry
- Mood disorders (e.g., major depressive disorder, bipolar disorder)
- Anxiety disorders (e.g., generalized anxiety disorder, panic disorder, PTSD)
- Psychotic disorders (e.g., schizophrenia, schizoaffective disorder)
- Substance use disorders and withdrawal syndromes
- Personality disorders
6. Emergency Medicine and Critical Care
- Basic and advanced life support (BLS/ACLS)
- Shock and sepsis management
- Toxicology and overdose management
- Trauma and burn management
- Airway management and mechanical ventilation
7. Preventive Medicine and Public Health
- Screening and prevention guidelines
- Epidemiology and biostatistics
- Infectious disease outbreaks and public health measures
- Vaccination schedules
- Occupational and environmental medicine
Study Tips for High-Yield USMLE Topics
1. Focus on First Aid and UWorld
First Aid for USMLE is a must-have resource for Step 1, and UWorld question banks provide detailed explanations that reinforce learning.
2. Use Anki for Active Recall
Spaced repetition with Anki flashcards helps retain high-yield facts and concepts.
3. Practice with NBME and UWorld Exams
Simulated exams help assess progress and identify weak areas.
4. Understand Concepts, Not Just Memorization
USMLE questions often test clinical reasoning rather than rote memorization.
5. Use Visual and Audiovisual Learning Aids
Videos from resources like Sketchy Medical, Pathoma, and Boards and Beyond help with complex topics.
Conclusion
Mastering high-yield topics for the USMLE is key to success. By focusing on these essential areas and using effective study strategies, you can optimize your preparation and achieve a high score. Stay consistent, practice regularly, and maintain a well-structured study plan to excel in your USMLE journey.Read more blog….
