The answer to this problem is not immediately obvious.  I'd suggest you actually calculate the mean, the mode and the median.  That's relatively easy.  Not so easy is making the connection between mean, mode or median to the advisability of studying harder for the next exam.  What's your reasoning?

If he wants to persuade the class to study harder he should choose the measure that shows the lowest measure of center.
