I think it depends, because the syllabus for what we are required to know now will be different compared to years ago. Just because it is different however, doesn't mean that it is any more difficult.
However, as a student, I'm going with no, I don't think exams have become easier. I think they have become more complex, as there is more for us to know now, and often they can be quite specific making essential details important.
I'm sure there are ways to fully compare this, but at the end of the day it could be down to personal preference and how well the individual themselves copes with exams and how prepared they are etc.
