How to Prepare for the DNB Practical Exam

Exam Structure (300 Marks Total, 4 Hours)

1. OSCE (Objective Structured Clinical Examination)

• Set up mock OSCE stations with peers, ideally timed at 4 minutes per station
• Cover a wide range of scenarios: spot diagnosis, interpret ECGs/X-rays/lab values, equipment identification, clinical reasoning questions, procedural steps
• Practice the think-aloud approach - examiners like to see structured reasoning
• For specialty exams (e.g., Pediatrics), expect stations on NRP/PALS scenarios, vaccine schedules (ACVIP/NIP guidelines), national programmes, and growth charts
• Focus on recent guidelines - these frequently appear as OSCE stations

2. Clinical Cases

• Practice presenting long cases in exactly 15-30 minutes (start, examine, summarize, suggest management)
• For most specialties, cases cluster around neurology and systemic conditions - know your most common and high-yield cases cold
• Use the structure: History → Examination findings → Differential diagnosis → Investigations → Management
• Present to seniors and mentors regularly - get feedback on clarity, timing, and gaps
• Know how to handle "difficult examiners" - if challenged on your diagnosis, don't fold immediately; defend with logic but remain open to correction

• Skipping negative findings (say what you did NOT find, not just what you found)
• Rushing examination without completing all systems
• Giving a vague management plan - be specific (drug doses, durations, monitoring)

3. Viva Voce

• Prepare crisp, structured answers for common viva questions in your specialty
• Revise recent advances - new drugs, updated guidelines, landmark trials
• Practice out loud with a study partner who can fire rapid questions
• For each major condition, know: pathophysiology, clinical features, investigations, management, complications, prognosis
• Revise clinical pharmacology - mechanism, doses, side effects, contraindications of common drugs

4. Ward Rounds

• Treat these like short cases - have a systematic approach to any presenting complaint
• Cover all sub-specialties you may encounter (ward rounds span 4 different sub-specialties)
• Practice bedside communication skills - speak clearly, show empathy, maintain structure

General Preparation Strategy

1. Know the exam pattern cold - no surprises on the day
2. Practice daily clinical examinations - inspection, palpation, percussion, auscultation with real patients or volunteers
3. Create a study timetable - divide time between OSCE prep, case presentations, viva prep, and ward round practice
4. Revise high-yield topics and guidelines - commonly tested conditions, emergency protocols, current national guidelines
5. Join a study group - peer teaching and mock exams significantly build confidence and identify blind spots
6. Read previous candidates' experiences - the Reddit thread on DNB practicals and specialty-specific forums (like DNB Pediatrics blog) are valuable for real insight
7. Physical and mental stamina - the exam is ~4 hours of intense performance; practice under similar time pressure

Day of the Exam

• Carry: stethoscope, pen torch, measuring tape, reflex hammer, and any specialty-specific instruments
• Dress professionally - formal attire creates a good first impression
• Stay calm between stations - do not let one poor station affect the next
• Every point counts - speak clearly and make every clinical observation explicit to the examiner
