Which of the following is not a characteristic of a good question paper?

Subjectivity is not a characteristic of a good question paper, since it lets personal bias affect marking.

A good question paper should minimise subjectivity so that scoring does not depend on the examiner's mood or opinion.

Objectivity is a desirable quality, ensuring that different examiners award the same marks for the same answer.

Reliability is desirable, meaning the paper yields consistent results across occasions and scorers.

Validity is desirable, meaning the paper actually measures what it is intended to measure.

Alongside these, a good question paper also needs practicability and comprehensive syllabus coverage.
