This diagram covers Selection and Iteration Flowcharts within Selection (IF Statements) for GCSE Computer Science. Revise Selection (IF Statements) in 3.2 Programming for GCSE Computer Science with 15 exam-style questions and 8 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 3 of 10 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.

Selection and Iteration Flowcharts

Selection and iteration flowcharts: left side shows an IF-ELSE flowchart with a decision diamond branching to two paths (True path and False path) that both rejoin below, right side shows a WHILE loop flowchart with a decision diamond where the True path loops back up and the False path exits the loop, demonstrating the structural difference between conditional execution and repeated execution
