It always makes sense to take a final examination seriously. If the exam turns out to be easy, wonderful. And if it's difficult, you're prepared. A strong exam performance can have significant redeeming value: if you're on the cusp between grades, it might be enough to decide things in your favor. And turning in a mediocre exam with the expectation that it won't affect your semester grade can backfire, even if your grade remains undamaged.
