⚖️ Weighted logic

Our grade predictor uses real weighted averages — exactly how professors calculate final grades. Input your weights, and we'll tell you the exact score needed.

🎯 Strategic planning

Whether it’s extra credit or a final exam, understand the impact before you commit. Decide where to focus your study time for max improvement.

🔒 100% private

All calculations happen inside your browser. No data is ever sent to servers — your grades stay with you.

📐 How grade calculations really work

Grade Predictor answers: “What do I need on my final assignments?” We calculate points earned so far, then find the missing points divided by remaining weight. It’s the same method academic advisors use.

Grade Improvement reveals how an extra assignment (retake, bonus paper) will shift your total. The calculator holds your current grade constant for unaffected weight, then adds the new score’s contribution.

Understanding weight distribution is key — a 5% quiz vs a 40% final exam change your strategy. Use our tool before every major exam.

📐 Official formulas

📌 Required score formula

Req% = (DesiredGrade% - (Current% × CompletedWeight%)) / RemainingWeight%

All percentages must be in decimal form (e.g., 85% → 0.85). CompletedWeight + RemainingWeight = 100%.

📈 Grade improvement formula

NewGrade = (Current% × (1 - NewWeight%)) + (ExpectedScore% × NewWeight%)

NewWeight = extra assignment weight (e.g., 10% = 0.10). Works for extra credit or replacing a low grade.

🎯 Real student scenarios

Crunching final exam target

Emma has 82% after 65% of coursework. She wants an 88% final. Remaining work weight = 35%.

Points earned: 82×0.65 = 53.3 → needed: 88 – 53.3 = 34.7 → required: 34.7/0.35 = 99.1%

⚡ Needs 99.1% — very challenging; consider adjusting target.

Extra credit worth it?

Liam at 78% overall, optional paper = 8% weight. He expects 90% on the paper.

Unchanged 92% × 0.78 = 71.76; new part: 90×0.08=7.2 → new grade = 78.96%

📈 +0.96% increase (almost 1 full point — could raise letter grade)

Mid-semester reality check

Sophia has 74% with 45% of course done. Wants 80% final. Remaining 55% weight.

Needed on rest: (80 – (74×0.45))/0.55 = (80 – 33.3)/0.55 = 84.9%

✅ Manageable 85% target — strategize study for high-weighted assignments.

💬 Frequent questions

What if my weights sum to less than 100%?

Always double-check syllabus. The calculator flags mismatched weights because accurate totals are crucial for reliable predictions.

Does it work for curved classes?

Curves shift based on class performance. Use this tool to understand raw score targets, and then check historical curve patterns.

How to handle multiple categories (quizzes, midterms)?

Average the grades within each category, then input their combined weight. Example: quizzes total =20%, average quiz score =88% → use as one input.

Should I aim exactly for the minimum required score?

Always add a safety margin (3–5%) — unexpected grading or stress can affect performance. Overprepare for confidence.

Does grade improvement consider dropping lowest scores?

For replacement policies, adjust your “current grade” manually. This calculator models adding brand-new points, not substitution.

How accurate is this predictor?

As accurate as your inputs. Use official grade weights from your syllabus, and update current grades after each assignment.
