Selection in pseudocode (iGCSE Computer Science)

This 19 page resource is designed to introduce students to the use of selection (conditional statements) in pseudocode, as required for the new iGCSE Computer Science specification (from 2023).

The first section covers comparison operators and logical operators. Each command is introduced with some examples and, where appropriate, is compared with equivalent commands in Python. Exercise A has 20 questions for students to practise working with these commands.

The next section focuses on IF statements. The different possible structures of IF statements are introduced with some examples and, where appropriate, are compared with equivalent commands in Python. Exercise B has 19 questions for students to practise writing algorithms that include use of IF statements.

The next section focuses on CASE OF statements. The different possible structures of CASE OF statements are introduced with some examples and, where appropriate, are compared with equivalent commands in Python. Exercise C has 19 questions for students to practise writing algorithms that include use of CASE OF statements.

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