How to study for GCSE Economics
Learn each definition and diagram as a causal model, practise calculations with units, apply evidence to the stated context and qualify conclusions with realistic trade-offs.
Core concepts
Concept 1
Money acts as a medium of exchange, unit of account, store of value and means of deferred payment.
Exam cue: Name the function of money illustrated by the context rather than listing all four.
Concept 2
Banks, building societies, insurers and the central bank help channel saving into borrowing and investment and support payment and risk management.
Exam cue: Trace an interest-rate change separately for savers, borrowers, consumers and producers.
Concept 3
Interest is a reward to saving and a cost of borrowing, so different rates affect household spending and firms' investment decisions.
Exam cue: Calculate interest from the stated principal, rate and period, then interpret the result.
