AQA A-level Maths is made up of six units – three at AS and three at A2. All units are available in the June series. There are four Core modules which make up two-thirds of the total qualification.
The optional modules are Decision, Statistics and Mechanics. Students can focus on one of these strands or study a mixture of any two. Decision maths involves networks, algorithms and sorting.
This resource provides several past papers and mark schemes for the Decision 1 paper. These documents are freely available on the AQA website.
