Answer-any / Mark Distribution Patterns

Statements like:

  • “Next, 2 mark … one total of 10 mark. Answer any five of the following”
  • “Next, answer any four of the following”
  • “Question number 25 is compulsory”
  • “Next, answer all the questions”

Mark distribution examples mentioned:

  • “Seven mark … total 14 mark”
  • “Two seven mark”
  • “Four mark … total 16 mark”
  • “Four mark … four attend”
  • “Two mark … one to five attend” (wording unclear, but indicates optionality/choice)

Long/Derivation/Diagram-Based Responses

  • Derive the equations of motion by the graphical method.
  • Explain Tyndall effect and Brownian movement with a suitable diagram.
  • Draw the structure of oxygen and sulfur atoms.
  • “Draw/diagram proper number … photo…” (wording unclear, implies diagrams are required).

Short Theory Definitions & Differentiations
