Which measure (mean, median, or mode) should Maria's social studies teacher use to convince Maria that she needs to study more regularly for her exams?

Question

I think if Maria needs to study more regularly, her grades must be quite bad which we can imagine it as the marks of her studies to be positively skewed. For positively skewed graph, mode<median<mean. so to encourage her to study more, I think her teacher will choose the mode of her marks as that's the lowest among all, which can show her how bad her results are and study harder next time.
