How does the Grade Calculator determine letter grades?

The Grade Calculator uses standard academic letter grade scales: A+ (97-100%), A (93-96%), A- (90-92%), B+ (87-89%), B (83-86%), B- (80-82%), C+ (77-79%), C (73-76%), C- (70-72%), D+ (67-69%), D (63-66%), D- (60-62%), and F (below 60%). These ranges are commonly used in high schools and universities across the United States.

What if my assignment weights don't add up to 100%?

The calculator will display a warning if your total weight doesn't equal 100% and prevent calculation until corrected. This ensures accuracy in your final grade. Common solutions include adjusting individual weights proportionally or adding an 'Other' category to account for missing weight percentage.

Can I include incomplete assignments in my calculation?

Yes, you can include incomplete assignments by entering 0 for the score and the maximum points possible. This helps you see how missing assignments affect your current grade and what scores you need on remaining work to achieve your target grade.

How accurate is the GPA calculation?

The GPA calculation uses standard conversion rates: A+/A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0.0. Some schools may use slight variations, so check with your institution for exact GPA scales.

Can I save my grade calculations for later?

While the calculator doesn't have a built-in save feature, you can use your browser's bookmark functionality to save specific calculations, or take screenshots for your records. The detailed breakdown shows all input values, making it easy to recreate calculations if needed.

What if my school uses a different grading scale?

The calculator uses the most common U.S. academic grading scale. If your school uses different ranges (such as different cutoffs for A grades or plus/minus distinctions), you can still use the calculator for weighted averaging and manually apply your school's specific letter grade scale to the percentage results.
