| - | - | - | - |
| Program Purpose and Function | 1 | 1 | Program shows good example of input, program functionality, and output. Also describes the overall purpose of the program well. |
| Data Abstraction | 0 | 0 | Doesn't show 2 different program code segments which involve lists and also didn't identify the variables being used.|
| Managing Complexity | 1 | 0 | I thought that the student did well in this aspect but collegeboard said that the student didn't show proper usage of a list in order to manage complexity in a program. |
| Procedural Abstraction | 1 | 1 | The student includes 2 different code segments and explains how the procedure affects the overall functionality of the segment. |
| Algorithm Implementation | 1 | 1 | Procedure doesn't include all necessary elements (sequencing, selection, iteration). |
| Testing | 1 | 0 | The student passes different arguments into the procedure and shows the results of each call. Collegeboard didn't agree with this one either. |

Post Grading Reflection:

I think me and Collegeboard are fairly in agreement over what the grading should look like. Over this grading process, One thing that I've learned is that a proper description is very important, as sometimes people will have a great submission but their explanation brings them down. Learning from this, I will make sure that I have clear explanations to avoid confusion and to get good grades.
