How to use this KNUST CWA calculator
- Enter each course's percentage mark and its credits. Names are optional. Add course gives you more rows.
- Enter failed courses too, and a retake as a new row with its new mark. Leave out deferred courses.
- To skip semesters you already have a CWA for, type that CWA and the credits it covers under CWA so far.
How KNUST works out the CWA
KNUST's regulations (amended version of 2003) set the Cumulative Weighted Average. It uses raw percentage marks, weighted by each course's credits, over every course registered up to that semester.
CWA = sum(percentage mark × credits) ÷ sum(credits)
Failed marks stay in, a retake is added as a new entry, and deferred credits are not loaded. KNUST's own worked examples print the CWA to 2 decimals: 1603 ÷ 34 = 47.15.
Worked example: a CWA of 60.80
This made-up example comes from GradeCat's research on KNUST's rule: four courses and 10 credits.
| Mark (%) | Credits | Mark × credits |
|---|---|---|
| 72 | 3 | 216 |
| 65 | 2 | 130 |
| 58 | 3 | 174 |
| 44 | 2 | 88 |
216 + 130 + 174 + 88 = 608, and 608 ÷ 10 = 60.80. That is a Second Class Upper, which runs from 60 to 69.99. The 44 counts like every other mark: KNUST keeps low and failed marks in the CWA.
KNUST classes
| Class | CWA |
|---|---|
| First Class | 70 and above |
| Second Class Upper | 60 to 69.99 |
| Second Class Lower | 50 to 59.99 |
| Pass | 45 to 49.99 |
Graduating needs a CWA of at least 45%. A CWA of 40.00 to 44.99 means probation.
CWA so far and a new semester
Made-up example: a CWA of 58.20 over 34 credits is 58.20 × 34 = 1978.8 weighted marks. A new semester of 608 over 10 credits makes (1978.8 + 608) ÷ 44 = 58.79. It is not the average of 58.20 and 60.80, because the 34 credits count for more than the 10.
What this calculator does not cover
- CWA to GPA: KNUST publishes no conversion, so GradeCat gives none.
- Programmes with their own rules: check your department if its handbook sets something different.
KNUST CWA FAQ
How do I calculate my CWA at KNUST?
Multiply each course's percentage mark by its credits, add these up over every course registered, and divide by the total credits. 608 over 10 credits is 60.80.
What CWA is First Class at KNUST?
70 and above. A Second Class Upper is 60 to 69.99, a Second Class Lower 50 to 59.99 and a Pass 45 to 49.99.
Do failed courses count in my CWA?
Yes. A failed mark stays in the CWA with its credits, and a retake is added as a new entry.
What is the lowest CWA to graduate?
45%. A CWA of 40.00 to 44.99 means probation.
Can I convert my CWA to a GPA?
KNUST publishes no CWA to GPA formula, so GradeCat does not make one up. Use the CWA your transcript gives.
