IGCSE Pseudocode Path

1. Inputs and Outputs

Use INPUT, OUTPUT, and variables to model real exam questions.

Sequence Data types

2. Selection Logic

IF, ELSE, and CASE statements with boolean conditions.

IF/ELSE CASE

3. Iteration

FOR, WHILE, and REPEAT UNTIL loops with counters.

FOR WHILE

4. Arrays and Files

Store lists, search algorithms, and simple file logic.

Arrays Files

5. Procedures and Functions

Decompose problems into reusable blocks.

Functions Parameters

6. Trace Tables

Follow algorithm steps and predict output.
