Academic Success 101: Understanding GPA, CGPA, and Percentage Scales

What's the difference between GPA and CGPA? How do you convert percentages to a 4.0 scale? Here's the ultimate guide for students.

Grading systems can be incredibly confusing, especially if you're applying to universities in different countries. Whether you're dealing with a 4.0 scale in the US, a 10.0 scale in India, or percentages in the UK, understanding your standing is crucial.

GPA vs. CGPA: The Difference

GPA (Grade Point Average) usually refers to your performance in a single semester or term. CGPA (Cumulative Grade Point Average) is the average of your GPAs across all semesters in your degree program.

Common Grading Scales

  • 4.0 Scale: Common in the US and Canada. An 'A' is usually a 4.0.
  • 10.0 Scale: Common in many international technical universities.
  • Percentage: The traditional raw score out of 100.

Converting between these requires specific formulas. To save yourself the math, use our Universal GPA Calculator to handle weighted averages instantly.
