How the grade is worked out

Points, a late penalty, then a letter.

The worked example: lab report 3Rubric83 / 100six criteriaOn time83%B1 day late−10%of the scoreFinal74.7%CThe worked example: lab report 3Rubric83 / 100six criteriaOn time83%B1 day late−10%of the scoreFinal74.7%C
Points over points give the percent; a late penalty takes a share of that percent, up to its cap; the scale turns it into a letter.

Points and percent

Add the points earned, including any extra credit, and divide by the points possible. Rubrics weight criteria by giving them more points, so a 30-point analysis section matters three times as much as a 10-point hypothesis.

Late penalties and scales

Many teachers take a percentage of the score off for each day late, up to a cap; some take points instead, and some do not accept late work. A common scale puts an A at 90 percent; others add plus and minus grades. The syllabus decides both, so set them to match it.
