In which example has the student not used self-assessment correctly?

Correct answer: Considering oneself permanently incapable after low marks

Useful self-assessment is specific, evidence-based, and directed toward improvement. A student may examine low marks, identify a weak topic, and change practice or study methods. Concluding that one is permanently incapable converts one result into a fixed and global judgment. It does not identify a correctable cause or suggest an action, so option D is the incorrect use of self-assessment.
