So instead you have the luck of the draw of what classes your HS wants to put you in and their crazy grading system?
My HS's GPA wasn't out of 4, for example. Also if you ended up in Mr. Boris's class instead of Mrs. Solomon, you basically automatically lost a whole letter grade.
Or STEM schools (presumably not all) where ‘mastery’ is the tracked objective, achieved when you scored 80% or higher on tests. However, when mastery is translated to standard scoring models/transcripts it’s recorded as 100%.
