In a college, some courses contribute more towards an overall GPA than other courses. For example, a science class is worth 4 points; mathematics is worth 3 points; history is worth 2 points; and English is worth 3 points. The values of the grade letters are as follows, A= 4, B=3, C=2, D=1, F=0. What is the GPA of a student who made a “C” in Trigonometry, a “B” in American History, an “A” in Botany, and a “B” in Microbiology?

In a college, some courses contribute more towards an overall GPA than other courses. For example, a science class is worth 4 points; mathematics is worth 3 points; history is worth 2 points; and English is worth 3 points. The values of the grade letters are as follows, A= 4, B=3, C=2, D=1, F=0. What is the GPA of a student who made a “C” in Trigonometry, a “B” in American History, an “A” in Botany, and a “B” in Microbiology?

Answer 1

I have never heard of a college doing this.

GPA= grade*weight + ...
= (2*3+3*2+4*4+3*4))/(4+3+2+4)=40/13=3.08

Answer 2

To calculate the GPA, we need to multiply the grade points earned in each course by the class weight, and then sum them up and divide by the total credit hours.

Given:
Trigonometry (C) = 2 points
American History (B) = 3 points
Botany (A) = 4 points
Microbiology (B) = 3 points

We also need to know the credit hours of each course to calculate the GPA. Please provide the credit hours for each course.

Answer 3

To calculate the GPA, we need to multiply the points earned for each course by the credit value of the course, then add up these values and divide by the total number of credits.

Given:
- Trigonometry: "C" grade (2 points)
- American History: "B" grade (3 points)
- Botany: "A" grade (4 points)
- Microbiology: "B" grade (3 points)

Now, let's calculate the GPA:

1. Assign credit values to each course:
- Trigonometry: 2 credits
- American History: 2 credits
- Botany: 4 credits
- Microbiology: 4 credits

2. Calculate the total points earned for each course:
- Trigonometry: 2 (grade points) * 2 (credit value) = 4 points
- American History: 3 (grade points) * 2 (credit value) = 6 points
- Botany: 4 (grade points) * 4 (credit value) = 16 points
- Microbiology: 3 (grade points) * 4 (credit value) = 12 points

3. Find the total number of credits:
- Total credits = 2 + 2 + 4 + 4 = 12 credits

4. Add up the points earned in each course:
- Total points = 4 points + 6 points + 16 points + 12 points = 38 points

5. Calculate the GPA by dividing the total points by the total credits:
- GPA = Total points / Total credits
- GPA = 38 points / 12 credits

Therefore, the student's GPA is 3.17 (rounded to two decimal places).
