  • Don’t attempt in sequence; attempt in priority order

4. The Method-Mark Strategy

4.1 Why Method Marks Get You 70% Even With Wrong Answers

  • Marks given for formula
  • Marks given for substitution
  • Marks given for rearrangement
  • Final answer only 1 mark usually

4.1.1 Required Structure

  • List known quantities
  • Match formula
  • Substitute with units
  • Round correctly
  • Add final unit

7. Formula Recognition and Rearrangement Strategy

7.1 Knowing What Is Given vs What Isn’t

  • Formula booklet provides basic kinematics
  • But not all electricity formulas
  • Not all energy relationships are provided
  • Refractive index formula must be memorised

7.2 The Three-Step Formula Method

  • Identify
  • Rearrange
  • Substitute

7.2.1 Rearrangement Types

  • Cross-multiplying
  • Taking square roots
  • Reversing proportionalities

8. Graph Question Mastery

8.1 Setting Up the Axes

  • Choose scale that uses >75 percent of space
  • Dependent variable on y-axis
  • Independent on x-axis

8.2 Plotting Points

  • Use small crosses
  • Avoid circles
  • Maintain equal spacing

8.3 Best-Fit Line Rules

  • Balance points visually
  • Avoid zig-zag lines
  • Use a ruler, not freehand

8.3.1 Gradient Calculation

  • Use the largest possible triangle
  • Mark Δy and Δx
  • Show values beside triangle
