About grade calculator
If you know your current grade and how much the final exam is worth, you can work out the score you need to reach a target.
Formula
Needed = (target − current × (1 − exam weight)) ÷ exam weight. If you have 78%, the exam is worth 40% and you want 85%, you need (85 − 78 × 0.6) ÷ 0.4 = 90.5%.
Use it for planning
If the needed score is above 100%, that target is out of reach and you should aim for a lower grade. It helps you split study time between subjects.
A worked example
You have 82 percent so far, the final counts for 30 percent and your goal is 85. You need (85 − 82 × 0.7) ÷ 0.3 = 92 percent on the final. To end with 80 percent, you would need about 75 percent.
Be realistic
If the required score is above 100, the goal cannot be reached with the final alone. Use the calculator to compare targets, then plan your study time to fit.
