Grade Recovery Calculator

Is the target still reachable? Three worked cases

Worked example: a current grade of 80% after 60% of the course with a target of 85% requires (85 − 80 × 0.60) ÷ 0.40 = 92.5% on the remaining 40%. Scoring 100% on everything left would finish at 88%.

Not reachable under ordinary percentage grading: a current 62% after 75% of the course with an 80% target requires 134%; the best possible finish with 100% on the remaining work is 71.5%. With a 70% target, the required remaining average is 94%.

Compare the required remaining average with your own recent performance and the course grading rules. There is no universal cutoff for what counts as a “realistic stretch.” A requirement above 100% is not reachable without extra credit, dropped work, grade replacement or another policy that changes the arithmetic.

Completed weight is the share of the final grade already graded, based on the syllabus weighting rather than the number of assignments. Dropped-lowest rules, category minimums or replacement exams can change the real result.

Formula

required remaining average = (target final grade − current grade × completed weight) ÷ remaining weight

Two final-grade goals can require very different scores on remaining work

1. Use a fictional course where 70% of the final grade weight is complete at a current weighted average of 76%, leaving 30% of graded weight. The completed work contributes 0.70 × 76 = 53.2 points toward the final percentage.
2. For an 80% final grade, solve (80 − 53.2) ÷ 0.30 = 89.333…%. The student needs an average of about 89.34% across all remaining weighted work to finish at or slightly above 80%, before any school-specific rounding.
3. For an 85% final grade, the same equation gives (85 − 53.2) ÷ 0.30 = 106%. Without extra credit or a grading rule allowing more than 100% on remaining work, that goal is unattainable under these assumptions.

What the result tells you

A modest change in the target shifts the required remaining performance from demanding but possible to mathematically out of reach. Use the calculator to choose an actionable target and check the syllabus rather than treating a projected number as a promise.

Before you use the result

The 76% must describe completed course weight, not merely an unweighted gradebook display. Category minimums, grade drops, missing assignments and late penalties may invalidate this one-bucket estimate.

• Recovering a course grade
• Planning the average needed on remaining work
• Checking whether a target is still mathematically reachable
