Nah they're legit finals, not like proficiency tests. Already took those. All I know is that your GPA and Final grades aren't intertwined. Probably because of bad test-takers and then we're back at the no-child-left-behind.
Not sure, I'm assuming no. It's just a pointless letter grade on the report card aside from your quarter grade. It might affect some things that are borderline, but idk I'm gonna need to find out though. Not my best year school wise lol.
