Answer: his overall GPA will be 2.93, which means he doesn't pass out with a 3.0 GPA
Step-by-step explanation:
GPA = 2.78
total credit hour = 105
Total credit unit = 105 x 2.78 = 291.9
If he takes a 15 credit hour and gets a perfect 4.0 GPA,
his total credit unit = 15 x 4 = 60
Final GPA = (291.9 + 60)/(105 + 15)
= 351.9/120 = 2.93
