CWA vs CGPA vs FGPA
The three averages sound like dialects of the same language. They are not: they are built from different ingredients, weighted differently, and classified on different scales. This page defines each one from its own university's documents — and then answers the follow-up question honestly.
The three, defined
CWA — Cumulative Weighted Average (KNUST)
The average of your percentage marks, weighted by credit hours, accumulated over every semester: total weighted marks ÷ total credits. KNUST's system contains no grade points at all — a 73 is worth 73 × its credits, full stop. One semester alone is called the WA; the running total is the CWA, and §12 of the Regulations classifies the degree on it.
CGPA — Cumulative Grade Point Average (UCC; also UG's standing figure)
The average of grade points: each mark is first converted by a table (at UCC, 80+ → 4.0, and everything below 50 → 0), multiplied by credits, and pooled across all courses as if in one semester. At UCC this pooled figure is the classifying average. At UG a CGPA also exists, but only as the unweighted standing figure used for progression — UG classifies on the FGPA instead.
FGPA — Final Grade Point Average (UG)
UG's classifying average: grade points averaged within each level first, then the four level GPAs weighted 1:1:2:2 — the last two years count double. It exists only at the end of the programme; before that, the same arithmetic over the levels you have is a projection.
"So what is my CWA in GPA?" — the honest answer
There is no official conversion, and this site will not invent one. KNUST publishes no table that turns a CWA into a GPA — its careful converters say the same — because the two numbers are not two names for one quantity. A mark average and a grade-point average compress the same transcript differently: grade points flatten distinctions inside a band (a 79 and a 75 are both "B+") and sharpen them at the edges (a 79 and an 80 are a full 0.5 apart). Any single conversion line drawn through that is a fiction with a formula.
What you can legitimately do: if another institution or employer asks for your standing, give them the figure your university actually awarded, in its own system, with its class — a First Class CWA of 74.20 needs no translation to be understood. If a form forces a 4.0-scale estimate, that estimate belongs to whoever demands it, computed by their stated method — not to a converter pretending KNUST published one.
The same transcript, three readings
Take a student whose marks cluster in the high 70s with one weak course at 47. At KNUST the 47 enters at face value and the CWA barely notices a single course among many. At UCC the 47 becomes 0 points — a hole the pooled average must carry at full credit weight. At UG it becomes 0.5 points, and when it happened matters: in Level 300 or 400 its level counts double in the FGPA. Three systems, three verdicts, all correct — under three different rulebooks. That is why the calculators here are separate, and why each one cites its own.
