How do I work out what I need on my final exam?

Subtract the grade you have already secured, your current grade times the weight of completed work, from your target, then divide by the exam's weight. This calculator does it for you and tells you if the required mark is achievable or already secured.

What if I need more than 100 percent?

If the required mark is over 100 percent, your target is no longer reachable with the exam alone, so you would need to lower the target or seek extra credit if available. The calculator flags this so you can set a realistic goal.

What if the result is zero or negative?

That means you have already done enough on earlier assessment that even a zero on the final would meet your target. You have secured the grade, though it is still worth sitting the exam well in case weightings or marks differ from your estimate.

Final Exam Mark Needed Calculator

This calculator works out exactly what you need to score on a final exam or assessment to reach your target grade, taking the anxiety and guesswork out of exam season. Most courses are made up of several pieces of assessment, each worth a percentage of the final grade: assignments, tests, projects and a final exam. By the time the exam arrives, you already know your marks on the work done so far and how much of the course that work is worth, so the only unknown is how well you need to do on what remains. This tool turns that into a single clear number. You enter your current grade, meaning your average mark on the work completed, the percentage of the course that work represents, and the final grade you are aiming for. The calculator figures out how much the remaining assessment is worth and the mark you need on it to hit your target. The result is genuinely motivating because it replaces vague worry with a concrete goal: knowing you need 72 percent to get an A is far more useful than hoping for the best. It also tells you the truth when a target is out of reach, if the mark required is above 100 percent, or already secured, if you have done enough that even a low exam mark still hits your target. Use it to prioritise your study across subjects, to decide where extra effort will pay off, and to set realistic goals. It assumes the remaining assessment is weighted as one block and that marks scale linearly, which is how most course grades work. Check your course outline for the exact weightings, then use this to plan your exam push.

Assumes the remaining assessment is one weighted block and marks scale linearly. Check your course outline for exact weightings.

How it works

The remaining exam weight is 100 minus the weight of work already done. Your secured contribution to the final grade is your current grade times the weight done. The mark needed on the final is the target grade minus that secured contribution, divided by the exam weight as a fraction. If the result is over 100 it is not achievable; if zero or less, your target is already secured.

Worked example

With a current grade of 68 percent on work worth 70 percent of the course, you have secured 47.6 percent of the final grade. To reach a target of 75 percent, you need another 27.4 percent from the exam, which is worth the remaining 30 percent. So you need 27.4 divided by 0.30, about 91.3 percent on the final, a tough but achievable goal.
