  4. Hanging vs strangulation - a perennial differentiating question every year.
  5. Ossification centres - especially wrist bones (Tanner's chart) and appearing/fusing ages.

Quick Revision Tips

  1. Neonatology is the highest-scoring chunk - especially APGAR, Ballard score, neonatal jaundice thresholds, and RDS management.
  2. Developmental milestones must be memorised in a table - do gross motor, fine motor, language, and social together for each age.
  3. Vaccine schedule (India NIS) - updated 2024 schedule; VVM and cold chain are PSM-Pediatrics crossover questions.
  4. Nutritional deficiencies - one question per major vitamin/mineral almost every year; Bitot's spots, Harrison's sulcus, Mees lines = image-based.
  5. Congenital heart diseases - know cyanotic vs acyanotic, X-ray findings, and one-line clinical differentiator for each.
  6. IMNCI protocol - overlaps with PSM; know the danger signs, age cutoffs, and management plans.
  7. Reference books: O.P. Ghai (Essential Paediatrics) for Indian context; Nelson's for depth; Harriet Lane Handbook (available in library) for quick reference values.
