Index laws are a core algebra and number skill tested at both foundation and higher tier. Higher-tier students must also handle negative and fractional indices, making this a topic that bridges number work with algebraic manipulation.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Multiplying the indices instead of adding them when multiplying powers with the same base
Thinking a negative index makes the answer negative rather than a reciprocal
Confusing fractional indices with fractions of a number
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Surds are irrational numbers left in root form and tested exclusively at higher tier. Students must simplify, add, subtract, multiply and rationalise surds, skills that also prepare them for A-Level mathematics.
NumberStandard form allows students to work with very large and very small numbers efficiently. It appears in science-context questions and is tested on both non-calculator and calculator papers across all exam boards.
AlgebraExpanding brackets (distribution) is a fundamental algebraic skill used across many topics. Students multiply each term inside the bracket by the term outside, progressing to double-bracket expansion and expressions raised to powers.
