Distribution by Bloom's Level

Number of questions at each cognitive level in the full 27,099-question dataset.

Fig 1. The dataset is naturally imbalanced, with L3 Apply and L4 Analyze dominating. L6 Create is the rarest level with only 620 questions, reflecting the difficulty of sourcing creative-level assessments.

Subject-wise Distribution

Question counts per subject, broken down by Bloom's Taxonomy level (L1–L6).

Fig 2. Stacked bar chart showing the cognitive-level composition of each subject. Physics leads with 5,294 questions (heavily L3 Apply), while Anthropology has the fewest (150). Subject-level imbalance reflects real-world assessment availability.
