And it sucks for all of you. Because I didn't have to take any finals when the rest of my classmates had, too. The professors letted me skip mine because I'm passing all of my classes with an easy 100%.
Seeing as how finals are normally 20% of the final grade or more, would seem very had to have 120% in the class unless you're getting a ton of extra credit.
In experience though, at least where our final grades are concerned, 20% makes no difference. 80% and above is nearly always an A, so if you've got 100% in your coursework, you're laughing... but only as long as the exam is worth 20% altogether.
