Comparison of grade average by year and study treatment arm. The test statistic (p-value) was calculated by t-test independent statistic, comparing the mean of the intervention arm to the control arm. Comparison of the number of successes by year and study treatment arms. The test statistic (p-value) was calculated by Chi-square statistic, comparing the intervention arms to the control.
