Common questions

How do I calculate my grade with weighted categories?

Multiply each category's score by its weight, add them up, and divide by the total weight of the graded categories. 92 at 20%, 85 at 20% and 78 at 40% give (1,840 + 1,700 + 3,120) ÷ 80 = 83.25%.

What do I need on my final to get an A?

Choose Final exam and type your grade now, what the final is worth and 90 for the grade you want. With 85% going in and a final worth 20%, you need (90 − 85 × 0.8) ÷ 0.2 = 110%, so an A is out of reach; an 80% final gives 84%.

How is a test score calculated?

Divide the number right by the number of questions and multiply by 100. With 3 wrong out of 25, that is 22 ÷ 25 = 88%, a B+.

What percentage is a B?

On the common scale, 80 to 89 is a B: 87 to 89 is a B+, 83 to 86 a B and 80 to 82 a B−. Your school's scale may differ.

How do I calculate a grade with points?

Type each score as points earned over points possible, such as 45/50, and leave the weights empty. The calculator adds all the points earned and divides by all the points possible.

Why is my grade different from the gradebook?

Teachers may drop the lowest score, round differently, or weight categories by the points in them rather than a fixed percentage. The gradebook is the official record.
