Examiners report
Most students could calculate the inflation rate, although occasional careless mistakes were observed. These errors included using the wrong base year in the denominator or failing to subtract one when using the formula "new value divided by original value". Additional mistakes that resulted in mark deductions were the omission of the unit (% in this case) and rounding down to less than two decimal points, as explicitly instructed on the exam cover page.
