Since the student's score is at a lower percentile in the fourth period class compared to sixth period class, it means that there were more students who scored higher in the fourth period class than in the sixth period class. Therefore, students in the fourth period class generally performed better on the exam than students in the sixth period class. Option A is false because it is the reverse of the right answer. Option B is false because it assumes a linear relationship between the percentiles in both classes, which may not be the case. Option C is false because it assumes an incorrect inverse relationship between the percentiles in both classes.
