Final Grade Calculator

How it is calculated

The tool finds the score you need on the final exam to reach a target course grade. It assumes the final counts for a share w (in percent) of the course, and the work done so far fills the remaining 100 − w. With current as your average on that earlier work and target as the overall grade you want, the formula is needed = (target − current × (100 − w) / 100) / (w / 100). All grades are on the same scale, normally 0 to 100. The weight must be above 0 and at most 100. The result is not capped, so a figure above 100% means that the target cannot be reached without extra credit, and a negative figure means you already meet it.

Common mistakes

• Entering the final's weight as 0.3 instead of 30; the weight is a percentage.
• Using the average of the final and the earlier work as the course grade, when the final counts for only its weight.
• Entering a letter grade or a grade-point value instead of the percentage average on the same scale as the target.
• Forgetting that other pending assignments are part of the "current" grade, so the weight of the final should only be what remains.
• Believing a result above 100 can be reached; it only shows that the target is out of range without extra credit.
