The person showed input, program functionality and output in the 12 second video. The written response described the overall function of the code and explained the purpose of the input and output
Data Abstraction
✓
✓
The person showed the variable used for storing the data. It was not a one element list, and the use of the list did not assist in fulfilling the purpose of the program.
Managing Complexity
✗
✗
No code for the program is shown inside this category
Procedural Abstraction
✓
✓
Procedural Abstraction and the application are shown, its contribution to the function of the program are also fully described
Algorithm Implementation
✓
✓
Code segment shows correct sequence, iteration, and selection with a for loop. Very well made and detailed and easy to recreate
Testing
✓
✓
Written response answers follow the criteria correctly

Comments
Program Purpose and Function
✓
✓
Video demonstrates input with program functionality, and outputs. The response describes the overall use and purpose for the program clearly with the functionality relating to the video. It also describes the input + output in the video
Data Abstraction
✗
✓
The first segment of the code does not show a list, only showing the function.
Managing Complexity
✓
✓
Written Response explains how the list manages complexity and segment demonstrates it managing the complexity
Procedural Abstraction
✓
✓
Two code segments both show how the procedure is being called. The description of the procedure is very detailed and shows how it overall contributes to the function.
Algorithm Implementation
✓
✓
Sequencing, and selection and iteration are in the program code segment. The steps on how the algorithm works is explained very well and clear.
Testing
✓
✓
Fully explains the two calls to procedure with conditions and results of each call are clearly stated (3c)
Reflection:
For Submission 1, Collegeboard did not give a point for the Program Purpose and managing complexity part of the grading because the purpose was not valid. They did award points to the rest of the grading requirements. However, I did award points to the program purpose and function thinking that it was good enough. After this examination, when I submit my project to college board I must go into deeper checks for the requirements I have for purpose and function. For submission 2 I took a point off for data abstraction, when in reality college board gave them credit. I thought that they should have screenshoted a variable of the list for the code segment. After these observations I believe I must practice grading other Performance tasks, to be prepared for when I do my own.
