Paper 2 at a glance

Paper 2 lasts 1 hour 45 minutes, carries 90 marks and is worth 50% of AQA GCSE Computer Science.

  • Data representation, including binary, images, sound and compression.
  • Computer systems, software, hardware and Boolean logic.
  • Networks, protocols, cyber security and defensive measures.
  • Relational databases, SQL and ethical, legal and environmental impacts.

Build connected explanations

Strong Paper 2 answers link a technical fact to the situation in the question. Revision should mix precise recall with calculations, comparisons and longer explanations.

  • Show each step in binary and storage calculations.
  • Explain how a security measure reduces a named risk.
  • Use accurate database field, record, key and relationship vocabulary.
  • Balance advantages and disadvantages before reaching a justified conclusion.

AQA-specific coverage

AQA topics sit beside the shared GCSE content, including decimal data units, Huffman coding, run-length encoding pairs, the four-layer TCP/IP model and SQL changes.

  • Coverage is checked against the current specification.
  • Revision includes several question types for each part of the course.
  • Question support opens the relevant Course Guide section.
  • A separate AQA Paper 2 practice paper is included.

Timed practice with saved work

The AQA Paper 2 practice paper uses a 105-minute timer and a 90-mark total. Autosave protects work as the learner moves through the paper.

  • Approved extra time is included when it has been set for the account.
  • Hints are not available during full timed practice.
  • Earlier attempts remain available for review.
  • Paper 1 and Paper 2 results stay separate.

Check the official AQA sources

AQA remains the authority for the specification and assessment rules. Computing, Covered provides separate explanations and original practice.
