Frequently asked questions
What if my category weights don't add up to 100%?
The calculator automatically normalizes your weights, so partial syllabi (or a quick "what if" scenario) still produce a correct proportional result.
What's the difference between this and the GPA Calculator?
This tool calculates your grade within a single class from weighted categories (homework, exams). The GPA Calculator converts final letter grades across multiple classes into a semester or cumulative GPA.
How is the letter grade determined?
This calculator uses a common standard scale (93%+ = A, 90-92% = A-, and so on). Your institution's actual scale may differ slightly — check your syllabus for the exact cutoffs.
Can I use this to figure out what I need on a final exam?
Yes — enter your known category scores, then adjust the final exam score field up or down to see what percentage you'd need there to reach a target overall grade.
