How this is calculated
Divide the points earned by the points possible and multiply by 100: 24 ÷ 40 × 100 = 60%. On the common 10-point-band scale that lands in the D- range — you'd have needed 36/40 to reach the A band.
Common questions
Is a 90 an A or an A-?
In plus/minus systems, 90–92 is typically an A- and 93+ is an A, which affects GPA (3.7 vs 4.0). In straight-letter systems, everything from 90 up is simply an A. This calculator shows the plus/minus convention because it's the most common — your syllabus decides which applies to you.
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.
