Overall Bloom's Score: 20/25
The distribution slightly over-represents Understand level questions while under-representing Remember level. This reflects the course's emphasis on conceptual understanding over pure memorization, which is appropriate for a college-level course.
Answer Quality Analysis
| Metric | Value | Target | Status |
|---|---|---|---|
| Questions with Examples | 21/65 (32%) | 40%+ | ⚠️ Below target |
| Questions with Source Links | 62/65 (95%) | 60%+ | ✓ Excellent |
| Average Answer Length | 40 words | 100-300 | ⚠️ Below target |
| Complete Answers | 65/65 (100%) | 100% | ✓ Perfect |
Answer Quality Score: 21/25
Answers are concise and focused. While shorter than the 100-300 word target, this reflects the FAQ's role as a quick reference rather than comprehensive explanations. Source links direct readers to detailed content.
