The most basic way is to add all your grades up, then count the number of assignments. Divide the total score by the number of assignments to get your average. For example, say you have a 90/100, 100/100, 90/100 which = 280 (out of 300) now divide by 3 which = approx. a 93%. But your teacher/professor may weigh your grades. For instance, your tests and papers may be worth 50% of your grade while homework is worth 25% and quizzes are worth 25% of your overall grade.
For weighted grades you multiply the grade you got by the % it is worth so if you got 85% on a test worth 20%, 78% on homework worth 20% and 84% on another test worth 60% the sum is (85 x 0.2) + (78 x 0.2) + (84 x 0.6) = 83% overall

How do you calculate if you will pass a class when the final is worth 20 percent of my grade?
(.8*Current Grade)+(.2*Exam Score)
If you have a 52 percent in science and the exam is worth 30 percent how much do you need to pass to get 50 and over?
If 50 is passing: right now the contribution towards the total grade is (.70)*52, so the total grade = (.70)*52 + (.30)*E [for the final exam grade]. If the target is 50 for the total grade, then 50 = (.70)*52 + (.30)*E, and solve for E = (50 - (.70)*52)/(.30) = 45.3333, so a grade of 46 would put the final grade over 50. By the way, the maximum possible grade of a 100 on the final will result in 66.4 for the total grade.
If there are 30 questions on a test and 10 are missed what is the final grade?
66.6
How do you calculate friability?
initial - final / initial x 100
How do i average my grade when my grade is a 84 and my final was a 73 the finals worth 25 how do i find out my grade?
Missing information - you need the worth (weight) for every grade, not just for some of them. The way you calculate this so-called "weighted average" is to multiply each grade by its weight, and add everything up. Then you divide by the total "weight". Example: exam 1: grade is 80; weight is 40. exam 2: grade is 70; weight is 60. 80 x 40 + 70 x 60 = 3200 + 4200 = 7400. Divide this by the total weight (40 + 60 = 100), and you get a weighted average of 74.
