## Subplot 1: Questions by Attempt (Bar Chart)
### Labels and Axis Titles
- **Title**: "Questions by Attempt"
- **X-axis**: "Attempt 1", "Attempt 2", "Attempt 3"
- **Y-axis**: "Number of Questions" (range: 0–700)
- **Legend**:
- Blue: "Correct"
- Orange: "Incorrect"
- **Spatial Placement**: Top-right corner
### Data Points
- **Attempt 1**:
- Correct: 474 (blue)

## Cross-Referenced Observations
1. **Legend Consistency**:
- All subplots with legends (Subplots 1, 4) have colors matching their respective data points.
- Confusion matrix and performance metrics use inferred color coding (blue/orange for confusion matrix, green for performance metrics).
2. **Spatial Grounding**:
- Legends are consistently placed in the top-right corner for Subplots 1 and 4.
- Confusion matrix and performance metrics lack explicit legends but use standard color conventions.
3. **Trend Verification**:
- Subplot 1: Decreasing trend in both correct and incorrect answers across attempts.
- Subplot 2: High true positives (340) and false positives (244) dominate the matrix.
- Subplot 3: Recall (0.914) and F1 Score (0.711) outperform other metrics.
- Subplot 4: Majority of questions are marked "Correct" (54.8%).
