How does weighted grading work?

Each grading category carries a fixed percentage of the total course grade. Your final grade is the sum of your score in each category multiplied by that category's weight. For example, if homework counts for 20% and you score 90%, that category contributes 18 points to your final grade. All category weights must sum to 100% for the formula to work correctly.

What if the required score is negative?

A negative required score means you have already secured your target grade, even scoring 0% on the final would not drop you below the target. You can still improve your grade by performing well, but the target is already guaranteed. The tool shows \"already secured\" with the current minimum course grade you have locked in.

Why must weights sum to 100%?

The weighted formula assumes all categories together account for 100% of the grade. If your entries sum to 95%, 5% of the grade is unaccounted for and the formula produces incorrect results. The validation indicator shows the current total at all times; adjust weights until they reach 100% before reading the result.

How do I handle a course where the lowest quiz score is automatically dropped?

Calculate your category grade excluding the lowest score before entering it into the tool. For example, if you have five quiz scores and the lowest is dropped, sum the four kept scores and divide by the total possible points for those four quizzes. Enter that percentage as your quiz grade. The tool works on the resulting category grade; the drop policy is applied before you enter the number, not by the tool itself.

What if my professor has not graded the midterm yet?

Leave that category at your best estimate, perhaps your performance on similar assessments, or the class average if it has been shared. Use the what-if slider to model a range of outcomes: what happens if the midterm comes back at 70%, at 80%, at 90%. Seeing the resulting course grade for each scenario tells you how much the ungraded midterm affects your situation and what final exam score you would need under each outcome. Update the estimate immediately once the actual grade is released.

Does the calculator adjust for classes on a pass/fail or credit/no-credit basis?

The tool calculates a percentage grade and maps it to letter grades using the scale you set. For a pass/fail course, identify the minimum percentage your institution requires for a \"pass\", typically 60% or 70% depending on the school, and use that as your target grade. The calculation itself works the same way; you are just setting a lower target threshold than you would for a graded course.

How this tool works

The final grade target calculator determines what score you need on a remaining assessment to achieve a target course grade. Formula: Required Score = (Target Grade - Current Weighted Average x Weight Completed) / Weight Remaining. For example: target 85%, completed 70% of course weight at 82% average -- Required = (85 - 82 x 0.70) / 0.30 = (85 - 57.4) / 0.30 = 92.0%. You enter each graded item with its score and its contribution weight as a percentage of the total course grade. The tool shows the current weighted average and the required score on the next specified assessment. Multiple remaining assessments can be added, with the required score split or targeted individually. Key assumption: category weights are fixed percentages of the total course grade and each category's performance is treated uniformly. If some assignments within a category are weighted differently from others, the average will be an approximation of the true weighted category score. Edge case: when the required score exceeds 100%, the target is mathematically unachievable from the current position. The tool flags this immediately and recalculates the highest achievable final grade assuming a perfect score on all remaining work, so you have a realistic ceiling. A required score above 100% is also the earliest signal to discuss grade recovery options with the instructor before the final assessment window.
