Lecture Notes: AP Computer Science Principles 2024 FRQ Overview

Introduction

• Overview of 2024 AP Computer Science Principles FRQs (Free Response Questions).
• Discussion on both Set One and Set Two.
• First year with a new style FRQ section.
• Exam duration: 3 hours (2 hours MCQs, 1 hour FRQ).

Set One Overview

Question 1: Program Input

• Focus on describing valid input to a program and the program's response.
• Example: When a user inputs data like an integer or string, discuss how the program processes it.
• Emphasize simplicity; one input is sufficient.

Question 2: Iteration and Procedure

Subpart A

• Describe what is accomplished by the first iteration statement in your personal project reference (PPR).
• Identify loops such as for loop or while loop.

Subpart B

• Write two different procedure calls and describe their behavior.
• Example: Inputting different data to see varying outputs, like correctly and incorrectly spelled Brawler names.

Subpart C

• Using a provided procedure, describe steps to check list elements' validity.
• Example: Use of a check validity procedure to validate each list element.
• Method: Loop through elements, update a counter, and compare it against total elements.

Set Two Overview

Question 1: User and Program Concerns

• Identify the target users of your program.
• Explain how the program addresses a specific user concern or interest.

Question 2: Conditional Statements

Subpart A

• Describe the first conditional statement in your procedure and its Boolean expression.
• Explain general procedure action when Boolean evaluates to false.

Subpart B

• Describe procedure call outcomes and write a different call with the same outcome.
• Discuss reasoning if a different call can't yield the same outcome.

Subpart C

• Identify parameters in your procedure and explain their use of abstraction.
• Example: Parameter simplifying complex data handling through abstraction.

Conclusion

• Set Two perceived as more challenging than Set One.
• Final thoughts on personal preference for Set One.
• Awaiting results until July.

Final Note

• Questions and further discussion encouraged.
• Thank you for attending.
