Programming Practice Exam
A full practice exam in the same format as the unit examination: 20 multiple-choice questions, then three flowchart-and-Python questions — with a separate answer sheet.
About This Paper
This practice exam has the same format as the Programming with Python examination: Section I has 20 multiple-choice questions (2 marks each), and Section II has three questions where you draw a flowchart and then write the Python code (20 marks each). Time yourself: allow 3 hours, and work without notes.
Work on paper (or on your computer for practical tasks), just as you would in the real assignment. Show all your working. When you have finished, mark your work with the answer sheet.

Use Flowchart F for questions 13, 14 and 15.
Flowchart F
Read this flowchart as text
- Terminator: Start (then → OUTPUT "Enter a mark (0-100)")
- Input/output: OUTPUT "Enter a mark (0-100)" (then → INPUT mark)
- Input/output: INPUT mark (then → mark is 0 to 100?)
- Decision: mark is 0 to 100? (X → mark >= 40?; No → OUTPUT "Invalid mark")
- Input/output: OUTPUT "Invalid mark" (then → Stop)
- Decision: mark >= 40? (No → [blank Y]; Yes → [blank Z])
- Input/output: [blank Y] (then → Stop)
- Input/output: [blank Z] (then → Stop)
- Terminator: Stop
13. In Flowchart F below, what is the best label for blank X?
- A) No
- B) Yes
- C) Stop
- D) Invalid
14. In Flowchart F, what should blank Y be?
- A) OUTPUT "Pass"
- B) OUTPUT "Invalid mark"
- C) OUTPUT "Fail"
- D) INPUT mark
15. In Flowchart F, what should blank Z be?
- A) OUTPUT "Fail"
- B) OUTPUT "Pass"
- C) OUTPUT "Invalid mark"
- D) mark = 40

- B) 1 4 7 10
- C) 1 2 3
- D) 3 6
Section II — Flowcharts and Python (3 × 20 marks)
Question 1 (20 marks)
