Asterisk Classes: Analyst’s Strategy

  • The 5-Mark Rule: In Biology, NO diagram = Max 3 marks. Draw first, then explain.
  • Table Format: Use tables for all “Differentiate” questions like C3 vs C4 plants.
  • Scientific Names: Underline biological names (e.g., Homo sapiens) for better presentation.
