Same weighted algebra
Uses needed = (target − current × (1 − w)) ÷ w with w = exam weight ÷ 100.

Required Exam Score Calculator
Enter current grade, exam weight, and target course grade. See the minimum score required on that exam.
Needed = (target − current × (1 − w)) ÷ w
Enter values to see the result
- 1
Current course grade
Percent standing on work already counted toward the grade.
- 2
Exam weight
How much of the course this exam is worth (percent).
- 3
Target grade
The overall percent you want after the exam.
Why compute the required score
Guessing “I need a 90 on the test” ignores how much the exam actually counts.
Any remaining exam
Midterm, unit test, or final. Weight is what matters, not the label.
Clear pass/fail of the target
Flags when you need over 100% or when you already have the target locked in.
When to use this tool
Unit tests with fixed weight
When the syllabus lists Exam 2 as 20% of the course.
Grade recovery
See the minimum to climb from a C into a B.
Study prioritization
Know whether a small bump or a large leap is required.
Required exam score formula
Needed = (target − current × (1 − w)) ÷ w
w = exam weight percent ÷ 100. Current grade must reflect completed work only.

Frequently asked questions
How do you calculate the required exam score?
needed = (target − current × (1 − w)) ÷ w, where w is the exam’s share of the course as a decimal.
Example: current 78%, exam 25%, target 80% → (80 − 78×0.75) ÷ 0.25 = 86%.
Can I use this for more than one remaining exam?
Only if you treat all remaining weight as one combined exam. For multiple categories with different scores, model them in the weighted grade calculator.
What if my current grade already includes a zero for the exam?
Recalculate current grade without that zero first. Otherwise the required score will be wrong.
How is this different from the final exam calculator?
Same math. Prefer final exam grade calculator when the remaining item is specifically the final.
