- Implement tests for the drafting of worked examples in `test_draft_examples.py`, ensuring well-formed drafts are generated for skills without examples, and that the model's responses are validated.
- Create tests in `test_teacher_review.py` to cover the teacher's review process of student answers, including handling review requests, score validation, and ensuring proper access control for teachers and students.
- Ensure that the tests cover various scenarios, including error handling and edge cases, to maintain robustness in the review and drafting functionalities.
