You can enter scores and grades many different ways, e.g.:
||Letter grades from your Grade Scale. (See Grade Scale for how it determines percent value.)
||Rubrics from your Grade Scale.
||Special Marks which you can customize.
|Show + extra credit, - late penalties, etc. Reports show scores exactly how you type them, e.g., "17+1" is calculated as 18 but displayed as "17+1" so students can see the adjustments. (Percents are out of the points possible, so if an assignment is out of 20 points, a score of 19-5% subtracts 5% of 20, not 5% of 19.)
||Blank scores indicate an ungraded assignment, so it is not calculated into the grade. (Blanks are not considered missing.)
The "Input as" menu on the screen lets you choose Points, Percents, or Grades/Rubrics. This is required only to interpret ambiguous scores like "4", which could mean 4 points, 4%, or a rubric 4. Otherwise scores like "B+" and "87%" are unambiguous, so the menu setting doesn't matter.
Note: This does not affect whether your grades are calculated as percents, grades, etc. — that is set on the screen.
