If we were to take a look at the problem we would see that the greatest difference would be the greatest difference from 0, either positive of negative;
Student A: 1 from 0,
Student B: 0 from 0,
Student C: 3 from 0,
Student D: 2 from 0
<em>As we see from the results, Student C has the greatest difference from before</em>
