Why Averaging SGPAs Can Misstate CGPA
A 24-credit semester should count more than a 16-credit semester. The arithmetic mean of SGPAs treats them as equal, which is usually wrong.
Some universities recompute CGPA from every course rather than from stored SGPAs. If a failed course was later excluded from a semester card, stored SGPA and true CGPA can diverge.
How Hemiley Combines SGPAs
Each row contributes SGPA × semester credits to a quality-point total. CGPA is that total divided by the sum of credits.
This matches the usual ‘weighted average of semester GPAs’ method when each SGPA was itself credit-weighted inside the term.

Why Choose Hemiley?
Hemiley weights SGPAs by credits instead of a simple mean.
It does not apply backlog, improvement, or scaling rules unless those already changed the SGPAs you type.
