While Level 1 focuses on basic scaling, Level 2 requires the ability to manipulate ratios as parts of a dynamic system. It emphasizes the "Constant Value" method and the use of proportionality constants to solve intricate word problems.
Syllabus & Core Question Types:
Income, Expenditure & Savings: Complex problems where ratios of income and expenditure are given for multiple individuals, requiring the calculation of individual savings (e.g., Income - Expenditure = Savings).
Coins and Currency: Problems involving the ratio of the number of coins and their total value (e.g., a bag containing 50p, 25p, and 10p coins in a specific ratio with a fixed total value).

Mixture and Alligation: Advanced problems where two mixtures with different ratios are blended to form a third, or where a portion of a mixture is replaced by a pure component.

Exam Pattern & Marking:
Total Questions: 50.
Ideal Duration: 60 Minutes.
Scoring: +1 for correct, -0.25 for incorrect.
