Percentages link directly to fractions and decimals and are tested extensively across all exam boards. Questions range from simple percentage-of-an-amount calculations to reverse percentages and repeated percentage change problems at higher tier.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Dividing by the final amount instead of the original in reverse percentage questions
Confusing percentage increase with the new total amount
Using additive rather than multiplicative methods for repeated percentage change
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Fractions form the backbone of GCSE maths, appearing in nearly every paper. Students must be confident adding, subtracting, multiplying and dividing fractions, as well as converting between improper fractions and mixed numbers.
NumberDecimal arithmetic is essential for real-world problem solving and calculator-based exam questions. Students need fluency with the four operations on decimals, place value understanding, and converting between decimals and other number forms.
Ratio, Proportion & Rates of ChangeCompound interest builds on percentage multiplier methods to model growth and decay over time. Students apply repeated percentage change to financial contexts, population growth, and depreciation problems.
