Unweighted GPA gives every course equal weight regardless of credit hours. Weighted GPA multiplies the grade by the credit hours for each course before dividing by the total — meaning a 4-credit course has more impact on your GPA than a 1-credit course. Most universities use weighted GPA.
It depends on your current cumulative GPA and the number of credit hours completed. The more earned credits you have, the harder it is to raise your cumulative GPA in a single semester. Use our Cumulative GPA Calculator to set a realistic semester GPA target and see how many semesters you need to reach your target GPA.
