Frequently Asked Questions
Everything you need to know about our grade calculator
How do I calculate my current grade?
Sum of (score × weight) / total weight so far.
Multiply each assignment score by its weight (%), sum all, divide by total weight assigned so far. Our calculator handles this automatically.
What score do I need on my final?
(Target - Current×(1-weight)) / weight = needed final score.
Formula: (Target grade - Current grade × (1 - final weight)) / final weight. If current is 85%, target is 90%, final is 20% weight: (90 - 85×0.8)/0.2 = 110% needed.
How do weighted grades work?
Categories have weights - higher weight = more impact on grade.
Each category (tests, homework, etc.) has a weight (%). Tests worth 50% count more than participation worth 10%. Total weights should equal 100%.
What is a curved grade?
Adjusted based on class average - varies by instructor.
Curved grades adjust scores based on class performance. If class average is 70%, the curve might add points so average becomes a C. Curves vary by instructor.
