Are you trolling? With a subject like Latin, the actual situation is that all the students are really good by the time you have only 20 students left in the whole country. The exam is probably not easy at all, and someone who didn't prepare well would get a much worse score.
You are assuming that it makes sense to make grading to a curve with a sample that is highly selective. It does not.
(I did not study Latin. Just as an item of curiosity, my country's public radio service YLE broadcasts regular radio news in Latin. You can listen and also read some of the stuff here: http://ohjelmaopas.yle.fi/1-1931339 )
