Question 1

What is NCEA AS 91075 about?

Accepted Answer

This standard asks you to write a plan (not the actual code) for a simple computer program that solves a real task. Your plan needs to show the variables you'll use, the logic and flow of the program, and how you'll test whether it works. You're demonstrating that you can think through a program before you write it.

Question 2

What do students need to do for AS 91075?

Accepted Answer

1. Identify and specify all variables you need, including what type of data each one holds (e.g., numbers, text, decimals) 2. Design the procedural flow of your program using actions, conditions (if/then logic), and control structures (loops, selections) 3. Create a set of test cases that show inputs you'll try and what outputs you expect 4. Communicate your plan clearly using diagrams, pseudocode, or precise written descriptions—not actual programming code 5. Make sure your plan logically solves the specified task without errors or unintended behaviours

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91075?

Accepted Answer

Achieved: Your plan specifies variables with their data types, includes actions and control structures that solve the task, and lists test cases with expected inputs. Merit: Your plan independently uses well-chosen actions and control structures that work correctly with no unintended behaviour, and includes test cases with both expected and boundary inputs (like edge cases). Excellence: Your plan is flexible and robust, with an effective procedural structure that's well-organised with no unnecessary repetition, and includes comprehensive test cases covering expected, boundary, and invalid inputs.

Question 4

What mistakes do students typically make in AS 91075?

Accepted Answer

1. Not specifying data types for variables clearly (e.g., saying 'number' instead of 'integer' or 'decimal') 2. Creating test cases that only check the 'happy path'—forgetting to test what happens with boundary values or invalid inputs 3. Writing pseudocode or actual code instead of a plan that communicates the structure and logic in diagrams, descriptions, or proper pseudocode format
