Flowchart symbols, drawing sequence, decision and loop flowcharts, and writing the same algorithms in pseudocode with IF, WHILE, FOR and REPEAT.
5 narrated scenes. Press play, listen and read along — the points appear as they are explained. Use ‹ Prev / Next › or the scene bar to jump to any scene.
Flowcharts and pseudocode are two ways of writing an algorithm before coding. Both must be exact, and both appear in Paper 02 and in the SBA.
Narration uses your device’s built-in voice. No sound? Switch to “Captions only” — the captions advance on their own.
Step through an algorithm line by line and watch the variables change.
Copy these into your notebook in your own words — that is how they stick.
START and STOP.
Parallelogram.
Rectangle for calculations.
Diamond with Yes/No.
Structured English with keywords.
Selection.
Repetition.
Must change inside a loop.

Question 1 [10 marks]
A program reads a student’s mark. If the mark is 50 or more it prints “Pass”, otherwise it prints “Fail”.
(a) (a) State the name of the flowchart symbol used for (i) a decision and (ii) input or output. [2]
(b) (b) Write pseudocode for the program. [5]
(c) (c) Describe how a flowchart shows the two possible outcomes. [2]
(d) (d) State one advantage of writing pseudocode before coding. [1]
