Overview

The AP Computer Science Principles (AP CSP) Create Performance Task (PT) is a significant portion of your exam score, accounting for 30% of the total. To excel, follow this interactive guide that breaks down requirements and provides tips for each part of the task.

Task Components Breakdown

Component 1: Program Code

Submission Requirements

Your program must:

1. Include input, processing, and output.

2. Use at least one list.

3. Contain a function with a parameter.

4. Include comments explaining functionality.

Tips

• Use a collaborative approach: Work with peers to debug and refine ideas.

• Double-check the code submission checklist provided by the College Board.

Interactive Exercise: Use the prompt below to practice writing a function that meets the Create Task requirements. Share it with a peer for feedback.

Prompt: Write a program that calculates the average of a list of numbers, includes comments, and demonstrates input, processing, and output.

Example Structure:

# This function calculates the sum of a list
# Input: A list of integers
# Output: Sum of the integers

def calculate_sum(numbers):
    total = 0
    for num in numbers:
        total += num
    return total

# Input example
my_list = [1, 2, 3]
print("The sum is:", calculate_sum(my_list))

Component 2: Video

Requirements

• Format: .mp4, .mov, .wmv, or .avi.

• Size: Less than 30 MB.

• Content:

  • Show program input.

  • Demonstrate functionality.

  • Show program output.

Tips

• Practice recording with free tools like OBS Studio or QuickTime.

• Avoid personal identifiers in the video.

• Focus on a clear, concise demonstration.

Interactive Exercise:

1. Record a test video of your program using your phone or a screen recording tool.

2. Share it with a friend and ask them to confirm that all required elements (input, functionality, output) are visible.

Component 3: Written Responses

Structure

Respond to four questions in a structured PDF:

Tips

• Be concise: Stick to the word limit.

• Use technical vocabulary like "parameters," "functions," and "iterations."

• Cite any external libraries or APIs you use.

Interactive Activity: Use this template to practice answering the written responses:

1. Purpose of the Program:

   • The program is designed to...

2. Development Process:

   • Collaboration helped because...

3. Algorithm Explanation:

   • The algorithm includes...

Review your responses with a peer or teacher to ensure clarity and completeness.

Final Checklist:

Interactive Idea: Break into small groups and review each other’s checklists. Use peer feedback to identify areas for improvement.
