📚 Understanding GPA
What is GPA?
GPA stands for Grade Point Average. It's a number that represents your average performance across all your courses. Most schools in the United States use a 4.0 scale, where 4.0 is the highest (straight A's) and 0.0 is the lowest.
How is GPA Calculated?
GPA is calculated using this formula:
GPA = (Total Grade Points) ÷ (Total Credit Hours)
For example, if you earned an A (4.0) in a 3-credit course, that's 12 grade points (4.0 × 3 = 12).
What's the Difference Between GPA and CGPA?
- GPA (Semester GPA): Your grade point average for one semester or term
- CGPA (Cumulative GPA): Your overall grade point average across all semesters
What is a Good GPA?
- 3.5 - 4.0: Excellent (honors, dean's list)
- 3.0 - 3.4: Good (above average)
- 2.5 - 2.9: Average
- 2.0 - 2.4: Below average (may affect academic standing)
- Below 2.0: Poor (academic probation risk)
Note: What counts as "good" depends on your goals. Graduate schools and competitive programs often look for GPAs of 3.5 or higher.
