How this is calculated
Divide the points earned by the points possible and multiply by 100: 20 ÷ 40 × 100 = 50%. On the common 10-point-band scale that lands in the F range — you'd have needed 36/40 to reach the A band.
Common questions
Do professors round up borderline grades?
Entirely at their discretion, and policies vary wildly: some round anything above .5, some round at .45, some never round, and some round only for students who attended office hours or showed improvement. If you're within half a point of a boundary, it is always worth a polite question — before finals week, not after grades post.
What GPA do I need for the Dean's List?
Most schools set Dean's List between 3.5 and 3.7 for the semester, with a minimum credit load (often 12+ graded credits). It's a semester GPA, not cumulative — one strong term can make the list even in a rebuilding year. Your school's exact cutoff will be published by the registrar.
