Testing and Maintainability — 20 Questions

A set of twenty exam-style questions designed to mirror the format and expectations of OCR GCSE Computer Science assessments for J277/02.

This resource covers two closely linked topics that students regularly lose marks on - testing and maintainability, with questions that reflect exactly how OCR assesses them: identifying and correcting logic errors in pseudocode, completing test plans, classifying test data, and applying maintainability techniques to given code.
Included:

20 carefully structured questions covering errors, test data types, iterative and final testing, comments, naming conventions, subprograms, and more
Full answers with mark allocations, written for students not teachers
Watch out boxes targeting the specific misconceptions flagged in OCR examiner reports
Stretch & challenge questions to push deeper understanding without going beyond the spec
OCR-style pseudocode throughout, so students see exactly what they’ll face in the exam

A practical, ready-to-use resource to support effective exam preparation and reduce marking workload.
