I am creating an application so that a Teacher can ask a question and all students can answer it by submitting their answer to a Perl program on a webserver.
Now for the first time i'm trying to do it the OO way, just to learn it.

Now i have a class Student, which has methods like SetAnswer
SetScore
GetAnswer
GetScore

Other classes are Teacher and Question.
Where would i put a method GetAverageScore, that would return the average scores per question? It does not fit into any of the classes. Is my choice of classes wrong?
