Calculation marks are some of the cleanest marks on the paper. The issue is not difficulty. It is skipping the formula, dropping the units, or rushing the sign on a percentage change.
The core calculations to know
- Elasticity
- Revenue
- GDP and GNI
- Percentage change
The Paper 2 method
- Write the formula
- Insert the numbers from the case study
- Show each step
- State the final value with the correct unit
If you want the two calculations that come up most often, revise elasticity and GDP and GNI first.
