## Overview

This calculator tells you the exact score you need on your final exam to finish the course with a target grade. Enter your current grade, your target course grade, and how much the final is worth — and the result is instant. If the required score exceeds 100%, the target is mathematically out of reach, which is itself useful to know before the exam.

## How to read your result

The headline figure is the score you must earn on the final exam. The three-bar outcome chart shows your minimum possible course grade (if you score 0 on the final), the required score bar (the score the final needs to reach your target), and your maximum possible course grade (if you score 100 on the final). A vertical line marks your target on each bar so you can see at a glance how much room you have. If the required score comes back above 100, the target is unreachable with any exam performance; if it comes back at 0 or below, your target is already secured regardless of the final.

## Method

The required final score is derived from the weighted-average course grade formula: course grade = current × (1 − w) + final × w, where w = finalWeight / 100. Rearranging to isolate the final exam score gives: required = (target − current × (1 − w)) / w. The best-case course grade assumes a perfect 100 on the final; the worst-case assumes 0. Both are computed from the same formula with the final score substituted in.

## Example

- **Setup:** Current course grade 78, target course grade 80, final worth 40% of the course.
- **Result:** Required final score: 83. Best possible course grade: 86.8. Worst case (score 0 on final): 46.8.

## Frequently asked questions

### What is the formula behind this calculator?

Course grade = current × (1 − w) + final × w, where w is the final weight expressed as a decimal. Solving for the final score gives: required = (target − current × (1 − w)) / w. This is the same formula used by RogerHub and Calculator.net.

### What does it mean when the required score is above 100?

It means your current grade is too low to reach the target no matter how well you do on the final. The maximum possible course grade is shown in the outcome chart — if that maximum is still below your target, the target is out of reach. Use this as early warning to adjust your target or speak with your instructor.

### What if the required score is negative or zero?

A negative or zero required score means you have already secured the target grade even if you skip the final (score 0). You still need to sit the exam if attendance is required, but your course grade is safe.

### How do I find my current grade and the final weight?

Your current grade is the cumulative score for all coursework completed so far, usually shown in your learning management system. The final weight is listed in the course syllabus — common values are 20%, 30%, or 40%.

### Does the calculator account for extra credit or dropped scores?

No. Enter your current grade after any drops or extra credit have already been applied by your instructor. The calculator uses a single current-grade value and a single final weight.
