Five Modules. Every Case Counts.
425 clinical cases across five high-yield specialties — built for real clinical decision-making.
Dermatology
Visual diagnosis meets clinical reasoning.
Identify and manage skin conditions across 9 categories. Each case presents a clinical scenario with image-based findings, requiring you to diagnose and select the appropriate management.
What you'll learn
- Recognize common and emergent dermatologic conditions
- Differentiate benign from malignant lesions
- Select appropriate first-line treatments
- Know when to refer to dermatology
Case difficulty
A 34-year-old woman presents with a 2-week history of an intensely pruritic rash on her wrists and ankles. Exam reveals flat-topped, violaceous papules with fine white lines on the surface.
What is the most likely diagnosis?
Heart Sounds
Train your ear. Save a life.
Master cardiac auscultation with synthesized real-time audio waveforms. Each case presents a clinical scenario and audio findings across four question phases.
What you'll learn
- Identify S1, S2, S3, and S4 heart sounds
- Recognize systolic and diastolic murmurs
- Correlate auscultation findings with diagnoses
- Grade murmur intensity and radiation
Case difficulty
A 68-year-old man with exertional dyspnea and syncope. On auscultation you hear a harsh crescendo-decrescendo systolic murmur at the right upper sternal border radiating to the carotids.
What is the most likely valvular lesion?
EKG Interpretation
Read the rhythm. Make the call.
Interpret electrocardiograms across 11 rhythm categories with color-coded strip visualizations. Cases range from benign variants to life-threatening arrhythmias.
What you'll learn
- Systematically interpret rate, rhythm, axis, and intervals
- Identify STEMI patterns and equivalents
- Recognize life-threatening arrhythmias
- Differentiate bundle branch blocks and conduction defects
Case difficulty
A 58-year-old man with crushing chest pain for 45 minutes. EKG shows ST elevation in leads II, III, and aVF with reciprocal ST depression in leads I and aVL.
What is the most appropriate immediate next step?
Acute Care
High stakes. No second chances.
Manage critical presentations across 13 organ systems. Cases simulate real emergency and inpatient scenarios requiring rapid diagnosis and decisive management.
What you'll learn
- Prioritize workup in undifferentiated critical illness
- Recognize sepsis, shock, and respiratory failure patterns
- Select appropriate empiric therapies under time pressure
- Know when to escalate care and consult specialists
Case difficulty
A 72-year-old woman is brought in with altered mental status, fever of 39.4°C, HR 118, BP 88/54, RR 24, and SpO2 92% on room air. She has a Foley catheter in place. Lactate returns at 4.2 mmol/L.
What is the most appropriate immediate intervention?
Lab Interpretation
The numbers tell the story.
Interpret CBC, CMP, LFTs, endocrine panels, lipids, and critical lab values in full clinical context. Each case integrates lab findings with history and exam.
What you'll learn
- Interpret complete metabolic and blood count panels
- Recognize critical lab values requiring immediate action
- Differentiate causes of anemia, electrolyte disorders, and liver disease
- Integrate lab trends with clinical presentation
Case difficulty
A 45-year-old woman presents with fatigue and pallor. Labs: Hgb 7.8 g/dL, MCV 72 fL, MCH 24 pg, ferritin 6 ng/mL, TIBC 480 mcg/dL, reticulocyte count 1.1%.
