Relative vs absolute grading: which does your university use?
Two universities can award the same letter grades but decide who gets them in completely different ways. Knowing which system yours uses explains a lot about your CGPA.
Absolute grading
Under absolute grading, the marks needed for each grade are fixed in advance: score above a set threshold and you earn that grade, regardless of how the rest of the class did. It is predictable — you can know exactly what you need — but it makes grades sensitive to how hard the paper was.
Relative grading
Under relative grading (often called grading on a curve), your grade depends on where you rank within the class. The top slice gets the highest grade, the next slice the next, and so on. This controls grade distribution and adjusts for exam difficulty, but it means your grade depends partly on your peers, not only on your own marks.
How to tell which you have
Check your examination ordinance or student handbook — relative grading schemes usually publish the percentile bands or the statistical method used. If grade cut-offs shift from one offering of a course to the next, that is a strong sign of relative grading.
Why it matters for your CGPA
Under relative grading, a high raw score does not guarantee a top grade if the class scored higher still — and a modest raw score can still earn a good grade in a difficult paper. This makes “what grade do I need” questions harder to answer precisely, because the threshold moves. You can still plan around it: enter your expected grades into the CGPA calculator using the grade you realistically expect to be awarded, not the raw marks you hope to score.
Planning under a curve you can't see
Relative grading makes “what do I need” questions genuinely harder, because the cut-off moves with the class. A workable approach: plan with the grade you realistically expect to be awarded, not the raw marks you hope to score, and build in a margin. Enter that expected grade in the CGPA calculator — planning against a conservative grade is safer than assuming a high raw score guarantees a top grade.
Key takeaways
- Absolute grading uses fixed mark thresholds; relative grading ranks you within the class.
- Shifting cut-offs between course offerings are a sign of relative grading.
- Under a curve, a high raw score doesn't guarantee a top grade, and vice versa.
- Plan with the grade you expect to be awarded, not the marks you hope to earn.
