OCR J277 GCSE Computer Science

OCR J277 homework and practice, ready to set

Set focused GCSE Computer Science practice across the OCR J277 specification. CS Ninja supplies the questions, marks the work and gives students another attempt at skills they miss.

For OCR J277 classes

Use CS Ninja throughout the two-year GCSE course for retrieval practice, topic homework and revision. Teachers can target a whole specification area or individual skills within it instead of building worksheets from scratch.

J277 Components 01 and 02

The question bank follows the breadth of the OCR specification and includes both computer systems and computational thinking content.

Systems architecture and storage

CPU structure, the fetch–decode–execute cycle, performance, memory, storage and embedded systems.

Data representation

Units, binary, hexadecimal, images, sound and compression.

Networks and security

Topologies, protocols, layers, network threats and prevention methods.

Algorithms and programming

Computational thinking, searching, sorting, programming constructs, arrays and tracing.

Robust programs and Boolean logic

Defensive design, validation, testing, truth tables and logic operators.

Software and wider impacts

Operating systems, utility software, languages, IDEs, legislation, ethics and environmental impacts.

Homework that adapts during the set

Choose a J277 area, select the required skills and schedule the assignment. Questions use generated values so students practise the method rather than memorising one answer. Wrong answers are explained and the underlying skill appears again later.

Useful across the GCSE course

  • Specification-organised topic selection
  • Multiple-choice and exam-style options by plan
  • Instant results for teachers
  • Independent public practice for students
