What is your GPA for the semester?



Answer :

To calculate your GPA for the semester based on your grades in various classes, we will follow these steps:

1. Identify the grade points for each letter grade:
- A: 4.0
- B: 3.0
- C: 2.0
- D: 1.0
- F: 0.0

2. List the classes with their respective credits and grades:
- MTH 1445: 4 credits, Grade A
- PSY 2000: 3 credits, Grade D
- ANT 3100: 4 credits, Grade A
- CHM 3230: 5 credits, Grade B

3. Calculate the grade points for each class by multiplying the credits by the grade points:
- For MTH 1445:
- Credits: 4
- Grade: A (4.0 grade points)
- Grade Points = 4 4.0 = 16.0

- For PSY 2000:
- Credits: 3
- Grade: D (1.0 grade points)
- Grade Points = 3
1.0 = 3.0

- For ANT 3100:
- Credits: 4
- Grade: A (4.0 grade points)
- Grade Points = 4 4.0 = 16.0

- For CHM 3230:
- Credits: 5
- Grade: B (3.0 grade points)
- Grade Points = 5
3.0 = 15.0

4. Sum up the total credits and total grade points:
- Total Credits: 4 (MTH 1445) + 3 (PSY 2000) + 4 (ANT 3100) + 5 (CHM 3230) = 16 credits
- Total Grade Points: 16.0 (MTH 1445) + 3.0 (PSY 2000) + 16.0 (ANT 3100) + 15.0 (CHM 3230) = 50.0 grade points

5. Calculate the GPA by dividing the total grade points by the total credits:
- GPA = Total Grade Points / Total Credits = 50.0 / 16 ≈ 3.125

Therefore, your GPA for the semester is 3.125, with a total of 16 credits and 50.0 grade points.
