Exponentials and logarithms test whether index and log laws are reflexes: simplifying a³·a⁴, converting between exponential and log form, solving equations by taking logs, and sketching y = aˣ and y = ln x with correct intercepts and asymptotes. Growth/decay word problems are usually one translation step plus one law.
Standard slips: log(a+b) split as log a + log b, forgetting domain restrictions (log of non-positive is undefined), and mishandling fractional or negative indices. State the domain before solving — it catches half the traps.
Study method: attempt five timed questions, log every miss with its topic code, redo misses from scratch within 48 hours, then re-attempt the topic a week later. Pair each hub with its drill link below and a fortnightly full mock.
Place this topic in the wider test with the syllabus checklist and Paper 1 vs Paper 2, learn the timing system in how to prepare, and check what scores mean in scores explained.
