To calculate the overall grade based on the provided letter grades (B, B, C, C), you can assign numerical values to each letter grade typically as follows:
- A = 4.0
- B = 3.0
- C = 2.0
- D = 1.0
- F = 0.0
Using this scale, the grades can be converted as follows:
- B = 3.0 (two instances)
- C = 2.0 (two instances)
Now, you can calculate the overall grade:
-
Convert each grade to its numerical equivalent:
- B: 3.0 (2 times) = 3.0 + 3.0 = 6.0
- C: 2.0 (2 times) = 2.0 + 2.0 = 4.0
-
Add these values together:
- Total = 6.0 (from B grades) + 4.0 (from C grades) = 10.0
-
Count the number of grades:
- Total number of grades = 4
-
Calculate the average by dividing the total by the number of grades:
- Overall Grade = Total / Number of Grades = 10.0 / 4 = 2.5
Now, convert the average back to a letter grade using the same scale. An average of 2.5 corresponds to a C.
Overall Grade: C
