Checklist:

• Design for Rubric
• Design for versioning in Rubric
• Design for Import for grades
• Implement all models
• Implement CSV importing (handle versioning)
• Create API for getting Student and Question's Rubric details
• Implement method for getting stats like average marks for rubric etc

Setup Demo:

1. pip install requirements.txt -r
2. python manage.py migrate
3. python manage.py createsuperuser --> To access admin
4. python manage.py runserver
5. Go to the admin and create a Grading Revision
6. python manage.py seed_db --> For creating dummy question, rubrics, and attempt

CSV imports

1. Use python manage.py import_grade_sheet <CSV_FILE_NAME> --revision <REVISION_ID> --attempt <ATTEMPT_ID to import CSV in the decided format.
2. Check Admin for necessary Updates

Student API

1. Hit http://localhost:8000/rubrics/student-performance/<student_id>?question=<question_id>&revision=<revision_id> to get the required JSON response

Other Analytics

1. Check out AttemptEvaluation.get_avg_marks for Average
2. Check out AttemptEvaluation.get_percentile_rank_for_student for percentile rank

Assumptions and Future improvements

• Can break down the app into one containing students and questions and the other containing the Rubric System
• Validations on the models
• Marks are assumed to be in the 6th Column. This can be derived from column name too.
• Marks are assumed to be int
• Maximum Levels are assumed to be 3 atm (only applicable for the import sheet)
• When a new revision is added for an attempt, import sheet contains all the marks, even those that were not updated
• The import sheet will contain IDs of the rubrics (assuming that they are coming from our own frontend client). Can be easily modified to take names
• Validation for things like finding cycles in the Rubric Tree
• Validation for Maximum Marks
• Validation that the rubrics being imported belong to the rubric tree for that question only
