Midterms!! You're driving me crazy!

Midterms are finished everybody!!! But... the scanner in my school ruined that happy moment! You know what, on Monday, Mam Intan, our IT teacher, said that no one passed that test and that means everyone failed! I only got 68 and the passing grade is 72.... That's impossible! There are a lot of clever guys in my class and I can't believe it that they only got 60 or 70... After she checked it again, actually it is the machine's fault or the computer's fault (our school checks the midterm by computer, not manually) and I got... 90, that's better!
And again.. this kind of "accident" happened again on Friday... my Bahasa Indonesia teacher said almost 80 % of my class failed on midterm, I only got... again 68, but I'm sure, I'm really sure that it was the machine's fault. It should be! Or my midterms will be the worst!!
