Your grading scale
The table of letters uses this scale. Your school's own scale decides your grade. Change any letter or number to match it.

How the score you need is worked out
Your class grade at the end is a mix of the grade you have now and the final. If the final counts for 30%, the grade you have now counts for the other 70%. So:
final class grade = grade now × 0.70 + final exam × 0.30
Turn that round to find the final exam score: take the grade you want, subtract grade now × 0.70, and divide by 0.30. With 84% now and a goal of 80%: (80 − 84 × 0.70) ÷ 0.30 = (80 − 58.8) ÷ 0.30 = 70.67%. The working line shows the same steps with your numbers.
Reading the answer
If you need more than 100%, the goal cannot be reached unless there is extra credit. If you need 0% or less, you will reach it even with a zero on the final. The table under the answer shows what you need for every letter on your scale at once.
Before you rely on it
"Grade now" should be your grade on everything except the final, using your class weights. If your teacher drops the lowest score, rounds grades or has a rule such as passing the final to pass the class, the real answer can differ. Use the weighted grade calculator to work out your grade now. The optional "what if" box shows the class grade a given final score would give you.
