Introduction to pseudocode (iGCSE Computer Science)

This 13 page resource is designed to introduce students to the basics of pseudocode, as required for the new iGCSE Computer Science specification (from 2023).

Section A covers input/output, mathematical operations, comments, declaring variables/constants, and assigning values. Each command is introduced with some examples and, where appropriate, is compared with equivalent commands in Python. Exercise A has 13 questions for students to practise working with these commands.

Section B covers strings and substrings, procedures and functions, declaring an array/list, and working with arrays/lists. Each command is introduced with some examples and, where appropriate, is compared with equivalent commands in Python. Exercise B has 15 questions for students to practise working with these commands.

Answers to the exercises are included, and answers to any examples are included in the teacher’s version of the resource.
