How do you calculate grade point averages?

Answer 1

Do it the same way you would calculate averages but a little different :

A=4

B=3

C=2

D=1

and

F=0

so you add up the grades you got depending on what those grades are and you calculate te sum by the number of classes you have

EXAMPLE:

an A,A,C,F,D,B =4+4+2+0+1+3 =14

14/6=2.333333...

Meaning your grade point average is 2.33

Answer 2

First, figure out what each grade is worth, in points. The school will have that information either somewhere on its webiste, or in its catalog. Usually, it's something like this:

A+ or A = 4.0 grade points, per semester credit hour

A- = 3.7 grade points, per semester credit hour

B+ = 3.3 grade points, per semester credit hour

B = 3.0 grade points, per semester credit hour

B- = 2.7 grade points, per semester credit hour

C+ = 2.3 grade points, per semester credit hour

C = 2.0 grade points, per semester credit hour

C- = 1.7 grade points, per semester credit hour

D+ = 1.3 grade points, per semester credit hour

D = 1.0 grade point, per semester credit hour

D- = 0.7 grade points, per semester credit hour

F = 0.0 grade points, per semester credit hour

So, then, let's say you've taken six 3-semester-credit-hour courses, for a total of 18 semester credit hours. (The number of semester credit hours actually only matters if all six courses are not of equal semester-credit-hour value. In this case, all six are, so we can use the easier divide-by-number-of-courses method.)

So, then, let's say you got one A, one A-, two B's, one B-, and one C+

So, that's...

A = 4.0

A- = 3.7

B = 3.0

B = 3.0

B- = 2.7

C+ = 2.3

First, add-up all the points: 4.0 + 3.7 + 3.0 + 3.0 + 2.7 + 2.3 = 18.7

Then, divide points by the number of courses: 18.7 ÷ 6 = 3.116667 or, rounded: 3.12

So, then, the GPA for those six courses is 3.12 which is higher than a B, but not quite a B+

However, the above only works so easily because all six courses are 3 semester credit hours each. Notice that each letter grade is worth a certain number of points, per semester credit hour. If one of the courses was worth only 2 semester credit hours, making all six courses no longer of equal value, then you have to do a least common denominator sort of thing and do it by semester credit hours, not number of courses.

But the rudiments are the same, regardless. Let's say, for example, that one of those B's was for a 2 semester credit hour course, instead of a 3 semester credit hour one. In that case, the math would be a little different than above, to wit:

A = 4.0 x 3 semester credit hours = 12.0

A- = 3.7 x 3 semester credit hours = 11.1

B = 3.0 x 3 semester credit hours = 9.0

B = 3.0 x 2 semester credit hours = 6.0

B- = 2.7 x 3 semester credit hours = 8.1

C+ = 2.3 x 3 semester credit hours = 6.9

Again, add-up the points: 12.0 + 11.1 + 9.0 + 6.0 + 8.1 + 6.9 = 53.1

Now add-up the semester credit hours: 3 + 3 +3 + 2 + 3 + 3 = 17

Then divide points by semester credit hours: 53.1 ÷ 17 = 3.123529 or, rounded: 3.12

So, then, the GPA's still 3.12, though it's a little stronger because one of the courses was worth one semester credit hour less than the other five.

There you go! Now you're a GPA-calculatin' whiz kid!

Answer 3

all you have to do first add all the numbers together. then you divide that number from how many grades there were and there's your answer.

Answer 4

A = 4, B = 3, C = 2, D = 1. Add all the scores from all classes and divide by the number of classes.
