Final answer:
To determine the GPA with 120 credit hours, 21 of which are 'F's and the rest 'A's, you would calculate the total points using a 4.0 scale and divide by the number of credit hours, resulting in approximately a 3.30 GPA.
Step-by-step explanation:
If you have a total of 120 credit hours and have received 'F' grades in 21 credit hours, with the rest being 'A' grades, calculating your GPA would typically use a scale where an 'A' is worth 4 points and an 'F' is worth 0 points. To calculate your GPA, you would multiply each grade by its credit hours, sum these products, and then divide by the total number of credit hours.
For instance, you have 99 credit hours of 'A's (120 total credit hours - 21 credit hours of 'F's) and 21 credit hours of 'F's. Following the standard 4.0 scale:
- 'A' credit hours: 99 hours * 4 points = 396 points
- 'F' credit hours: 21 hours * 0 points = 0 points
Now, add the points together:
Total points = 396 points (from 'A's) + 0 points (from 'F's) = 396 points
Then, divide by the total credit hours to find the GPA:
GPA = Total points / Total credit hours = 396 points / 120 credit hours = 3.30
So, in this case, your GPA would be approximately 3.30, which is a strong GPA in many college grading systems.
