As a surgeon,
I want to use tests to check my understanding of a topic,
so that I can identify what I need to review or practice further.
As a surgeon,
I want tests to feel low-pressure and private,
so that I can answer honestly without fear of being evaluated.
As a surgeon,
I want to complete practical tasks on 3D anatomical models during tests,
so that I can validate my procedural understanding, not just theory.
As a surgeon,
I want to repeat tests and 3D tasks multiple times,
so that I can track my own improvement over time.
As an education provider,
I want self-assessment to support learning without formal grading,
so that users focus on improvement rather than performance.
