Grade calculator, and what you need on the final.

Add each part of the course, like homework, quizzes and tests, with its weight and your score, and see your current grade. Then type how much the final exam counts and the grade you want, and the calculator tells you the score you need on the final, plus where you end up with 100% or 0%. Letter grades use the common 90, 80, 70, 60 cut-offs; your class may use others.

Questions

Good to know.

How do I calculate my grade?

Add each category with its weight and your average score in it. The current grade is the weighted average.

What score do I need on my final?

Type how much the final counts and the grade you want; the calculator shows the score you need.

What if the weights do not add up to 100%?

They are scaled so they count as 100%, and the page tells you.

What if I need more than 100%?

Then the grade is out of reach unless there is extra credit.

Which letter grades are used?

A 90 and up, B 80, C 70, D 60. Check your syllabus.
