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?

Note that the first 3 scores,  10, 15, 25, are MUCH lower than the next score (75).  These 3 very low scores are really going to mess up the mean of the scores.
