Table 2. End-of-year survey responses.

All values are mean ± standard deviation. Three-point ordinal ratings responses were converted to numerical points: agree = 3, neutral = 2, and disagree = 1. A mean score ≥2.5 indicates that most students “agreed,” between 1.5 and 2.49 indicates most students remained “neutral,” and ≤1.49 indicates most students “disagreed.”
