1. Understanding the Structure of Paper 2 and Paper 4

1.1 Format Overview

  • Paper 2 (Core/Extended Theory)
    • Short structured questions
    • Long structured questions
    • Mixed calculations and explanations
  • Paper 4 (Extended Theory)
    • Higher-level structured questions
    • Multi-step reasoning
    • Graph work
    • Complex calculations and application-based explanations

1.2 Nature of Questions

  • Direct recall
  • Quantitative calculations
  • Multi-part logical progressions
  • Graph interpretation
  • Experimental situations
  • Explanation-based reasoning

1.2.1 What Makes These Papers Difficult

  • Long chains of reasoning
  • Overlapping concepts
  • Hidden marks in intermediate steps
  • Multi-skill integration within one question

2. The 4-Phase Attempt Method for Theory Papers

2.1 Phase 1: Question Scan (First 90 Seconds)

  • Identify:
    • All small 1–2 mark recall parts
    • All calculation-based questions
    • All diagrams and graphs
    • Long multi-part questions
  • Mark visually:
    • Easy/clear questions → attempt first
    • Dense reasoning questions → mid-phase
    • Graphs → reserve time (extra 3–4 minutes)

2.2 Phase 2: High-Surety Questions First

  • Quick recall items:
    • Definitions
    • Units
    • Basic formulas
    • Standard diagrams
  • Benefits:
    • Bank fast marks
    • Builds confidence
    • Reduces time pressure early

2.2.1 Sub-Parts Strategy

  • For a (a)(b)(c) type format:
    • Always solve (a) first (recall marks)
    • If (b) is unclear → skip → return later
    • Do not stay stuck longer than two minutes

3. Understanding the Marking Logic Before Attempting

3.1 How Marks Are Awarded

  • Step-by-step structure
  • Formula → substitution → unit
  • Logical reasoning
  • Cause–effect chains
  • Precision of vocabulary

3.2 Why Long Explanations Do Not Work in Physics

  • Examiners use keyword-based awarding
  • Long sentences hide missing keywords
  • Clear, short bullet-like lines are superior

3.2.1 Scoring Rules Across Papers

  • Calculation marks = method marks + accuracy marks
  • Explanation marks = concept + reason + result
  • Diagram marks = clarity + correct labels

4. The Calculation Workflow That Maximises Marks

4.1 The Three-Step Calculation Method

  • Step 1: Write formula
  • Step 2: Substitute values with units
  • Step 3: Solve and attach final unit

4.2 Rearrangement Strategy

  • Perform algebra before substituting
  • Use consistent layout:
    • Cross-multiply
    • Isolate variable
    • Insert values afterward

4.3 Common Calculation Traps

  • Mixing cm/m
  • Forgetting to convert mA/A
  • Incorrect rounding
  • Sign mistakes in vector quantities

4.3.1 Significant Figures Rule

  • Final answer → match least precise data
  • Intermediate steps → 3 significant figures
  • Avoid premature rounding

5. Structure-Based Strategy for Multi-Part Questions

5.1 Breaking Down Complex Questions

  • Identify what each part is testing:
    • Concept recall
    • Formula application
    • Reasoning
    • Interpretation
    • Graph analysis

5.2 Using the “Answer Map” System

  • Read entire question first
  • Create mini-outline:
    • What is known?
    • What is required?
    • Which formula links them?

5.3 Linking Answers Across Parts

  • Sometimes (b) depends on (a)
  • Use your result even if wrong
  • Examiners mark method, not accuracy

5.3.1 Avoiding Logical Breaks

  • Keep steps in clear sequence
  • Do not jump reasoning
  • Avoid vague transitions

6. The Diagram Strategy for Physics Theory Papers

6.1 Forces Diagrams

  • Use straight arrows
  • Place arrows at exact points of action
  • Label each arrow:
    • Weight
    • Normal
    • Friction
    • Tension

6.2 Circuit Diagrams

  • Use correct symbols
  • Ammeter in series
  • Voltmeter in parallel
  • Avoid crossing wires unnecessarily

6.3 Wave Diagrams

  • Equal crest-to-crest spacing
  • Straight principal rays
  • Correct arrow directions

6.3.1 Labelling Technique

  • Place labels parallel to diagram lines
  • Use neat horizontal labeling lines
  • Avoid diagonal labeling

7. Handling Graph Questions in Paper 4

7.1 Setting Up the Axes

  • Identify dependent variable → y-axis
  • Identify independent variable → x-axis
  • Choose scale using full width & height

7.2 Plotting Points

  • Use neat crosses
  • Avoid circles
  • Maintain uniform spacing
  • Recheck outliers

7.3 Drawing Best-Fit Line

  • Must balance points
  • Avoid kinks or zig-zags
  • Use ruler only

7.3.1 Gradient Calculation Method

  • Draw largest possible triangle
  • Mark Δx and Δy explicitly
  • Use values from triangle, not small local points
  • Attach correct unit to gradient

7.4 Interpreting Graph Features

  • Constant slope → uniform rate
  • Changing slope → acceleration
  • Intercept meaning: physical value at zero

8. Experimental Application Questions

8.1 Variable Identification

  • Independent variable
  • Dependent variable
  • Controlled variables

8.2 Measurement Techniques
