Cambridge IGCSE Computer Science (0478): Data Representation — Fillable Questions and Mark Schemes Support topic revision and exam preparation with this paired PDF resource for Cambridge IGCSE Computer Science (0478), Paper 1. The pack brings together Data Representation practice questions and corresponding mark schemes, allowing students to complete their work digitally, review their responses and identify areas for improvement. What is included? Fillable questions PDF: students can type their responses directly into the provided answer fields using a compatible PDF reader. Corresponding mark schemes PDF: supports checking answers, self-marking and reviewing the points required in a response. A paired practice-and-review format: keeps questions and marking guidance in separate files, allowing students to attempt the work before consulting the answers. How can it be used? The pack is suitable for classroom practice, homework, independent revision and teacher-supported intervention. Students can work through selected questions during a lesson or complete sections independently before reviewing their answers. A suggested approach is to: Attempt the questions without referring to the mark scheme. Compare responses with the marking guidance. Identify missing points or gaps in understanding. Improve answers and revisit questions that require further practice. Teachers can also use selected questions to check understanding, guide feedback or focus revision on areas where students need additional support.
