Key Patterns Identified

Pattern 1: Rotational Emphasis

Exam papers show rotational emphasis where topics cycle in dominance:

  • 2022/23: Balanced mix
  • 2023/24: Kinetics dominated (58%)
  • 2024/25: Electrochemistry dominated (28%)
  • Prediction: 2025/26 may emphasize Ionic Equilibria or Thermochemistry

Pattern 2: Course Structure Split

  • FAD1007 (Chemistry 3): Physical chemistry focus
  • FAD1008 (Chemistry 4): Organic chemistry focus
  • FAD1018 combines both but varies emphasis year to year

Pattern 3: Ionic Equilibria is King

  • Appears in every paper
  • Average 13-20% mark weight
  • Most reliable topic for guaranteed marks

Pattern 4: Organic Chemistry Concentration

  • Organic topics collectively = 35% of marks
  • Stereochemistry + Carboxylic Acids + Aldehydes/Ketones + General Organic
  • High-mark questions when they appear

Pattern 5: No Surprises

  • All exam topics appear in tutorials
  • No "surprise" topics outside curriculum
  • Thorough tutorial revision covers everything
