To calculate an overall grade based on the individual grades you've provided (B, B, C, D), we can assign grade points to each letter grade. Here’s a common scale:
- A = 4.0
- B = 3.0
- C = 2.0
- D = 1.0
- F = 0.0
Now, let's convert each letter grade to grade points:
- B = 3.0 (2 instances)
- C = 2.0
- D = 1.0
Next, we calculate the total grade points:
- Total Grade Points = (3.0 + 3.0 + 2.0 + 1.0) = 9.0
Now, we'll divide by the number of grades:
- Number of Grades = 4
- Average Grade Points = Total Grade Points / Number of Grades = 9.0 / 4 = 2.25
Now we convert the average grade points back to a letter grade. According to the common scale, an average of 2.25 typically corresponds to a C.
Overall Grade: C
