Computer Science 7516 Paper 1 June 2019, AQA AS-Level Past Papers with Mark Schemes

The exam evaluates algorithm design, programming proficiency, and problem-solving in computer science. Topics include local versus global variables, hand-tracing sorting algorithms, and binary numeral conversions. Programming tasks involve implementing algorithms for numeric outputs, enhancing error messages, and debugging skeleton programs. Game logic is explored through state transition diagrams, data structure management, and subroutine modifications. Tasks address board game mechanics like valid moves, score calculation, and piece promotion. Advanced challenges include implementing logic for opponent piece removal and integrating score evaluation. Analytical skills and structured programming are emphasized through iterative and conditional logic in dynamic gameplay scenarios.
