Do the weights need to add up to 100?

No — the calculation divides by the total weight you enter, so it works whether your weights sum to 100, add to some other total, or you've only entered the assessments completed so far.

What letter grade scale does this use?

A standard scale: 90+ is A, 80–89 is B, 70–79 is C, 60–69 is D, below 60 is F. Your institution's actual cutoffs may differ — check your syllabus for the exact scale used.

Can I use this to figure out what I need on my final exam?

Yes — enter your completed assessments as normal, then add a row for the final exam with your target overall grade in mind, adjusting the exam score field until the total matches your goal.

What if an assessment was extra credit and doesn't fit the weighting?

Extra credit doesn't always fit a clean weighted-average model — check with your instructor on how it factors into your final grade, since practices vary (some add flat points, others weight it as a small separate category).

Can I remove an assessment row I added by mistake?

Yes — you can delete an individual assessment row without needing to restart the whole calculation.

Plan your study allocation across courses to maximize academic standing.

Mathematical Formula & Methodology

Here is the standard mathematical equation used to calculate this result accurately:

\text{Final Grade} = \sum (\text{Assignment Score}_i \times \text{Category Weight}_i)

Formula Variables Explained:
Calculates weighted course grades across homework, quizzes, midterms, and calculates required final exam scores to earn a desired letter grade.

Step-by-Step Worked Example

With 85% homework (20% weight), 90% midterm (30% weight), needing a 90% overall: $\text{Required Final Exam Score} = \frac{90 - (17 + 27)}{0.50} = 92\%$

Maximize Your Results

Credit Weight Priority: Focus extra study hours on courses with higher credit weights, as they have a larger mathematical impact on GPA.
Review Syllabi: Confirm whether your school uses standard 4.0 or plus/minus (4.33) grading scales.
Track Midterm Progress: Calculate required final exam marks early to eliminate end-of-semester guesswork.
