UNIT OVERVIEW

This revision unit brings together everything you learned in Term 3. You will revise six major topics and practise mixed questions to prepare for assessments.

What you will revise:

• Distance, midpoint, and gradient formulas in analytical geometry
• Simple and compound interest, including hire purchase and depreciation
• Measures of central tendency and spread for grouped and ungrouped data
• Box-and-whisker diagrams
• Trigonometry in right-angled triangles
• Euclidean geometry theorems and proofs
• Volume and surface area of 3D shapes

Why these topics matter:

• Finance formulas help you understand loans, savings, and how money grows or loses value
• Statistics skills let you analyse data in sports, health, and business
• Analytical geometry and trigonometry are used in construction, surveying, and navigation
• Measurement calculations are essential for design and engineering
