OCR GCSE (J277) Paper 2 exam revision unit

For use after students have had a substantial programming experience, this is a set of exercises to prepare students for paper 2: Designing, Writing, Testing and Refining algorithms.

In year 11 we change the focus to honing computational thinking skills, preparing students for examination questions.

We provide a variety of resources in this download for you to use as you see fit.  Every student and class will be different, so we haven’t outlined any suggested way you should work through these exercises, simply dip in as you see fit, and mix and match what we have provided to suit.

All our activities are designed to tackle one of the four question focus areas from the specification for paper 2, Design, Write, Test and Refine.

Examples of activities included are:

  • Identifying appropriate data types
  • Designing solutions to problem by producing:
  • Pseudocode
  • Flowcharts
  • Refining algorithms written in:
  • OCR Exam Reference Language
  • Flowcharts
  • Natural English
  • Using trace tables
  • Identifying appropriate test data
  • Creating test plans
  • Writing algorithms from scratch based on scenarios in:
  • OCR Exam Reference Language
  • High-level language

This topic covers:

  • J277/02 “Computational thinking, algorithms and Programming” from the specification
