What Average Do I Need Next Semester?
"What do I need?" is a backwards question: your target class fixes the total your degree must reach, your completed work has already banked part of it, and the difference — divided by what is left — is the average you must now run at. Worked three ways, including the case where the honest answer is that the target has closed.
The formula: required average = (target × total work − marks already banked) ÷ work remaining. For UG, "work" is measured in level weights (1:1:2:2), not credits.
Case 1 — KNUST: reachable, but steep
Banked: 5,460 weighted marks over 84 credits (CWA 65.00). Left: 36 credits. Target: First Class — 70.00 over the final 120 credits needs 8,400 weighted marks. Still to earn: 8,400 − 5,460 = 2,940 over 36 credits = 81.67 per course-credit. That is an A-average in every remaining course: possible, demanding, and worth knowing now rather than in your final semester.
Case 2 — KNUST: the target that needs 150%
Banked: 4,800 weighted marks over 96 credits (CWA 50.00). Left: 24 credits. Same target: (8,400 − 4,800) ÷ 24 = 150.00. No effort changes that arithmetic — the marks needed exceed the marks that exist. The useful question becomes: what is the best still open? Perfect remaining work gives (4,800 + 2,400) ÷ 120 = 60.00 — Second Class Upper. A planner that printed "you need 150%" and stopped would be lying by omission; ours leads with the ceiling you can actually defend.
Case 3 — UG: the double-weighted last level
Banked: L100 3.10 (weight 1), L200 3.30 (1), L300 2.90 (2) — weighted sum 12.20. First Class needs an FGPA of 3.60, i.e. a weighted total of 21.60. Level 400, weight 2, must supply 9.40 → a GPA of 4.70 — impossible. Best finish: (12.20 + 2 × 4.00) ÷ 6 = 3.37. Second Upper (weighted total 18.00) needs (18.00 − 12.20) ÷ 2 = a Level 400 GPA of 2.90 — thoroughly reachable. Notice how the weight does the damage and the rescue: Level 400 moves the FGPA twice per grade point, in both directions.
How to use an answer like this
- Required average near your current one: hold your standard; the risk is drift, not heroics.
- Required average well above it (Case 1): the target is a stretch goal — plan your semester around it, and know the exact week it closes if results slip.
- Target closed (Cases 2 and 3): re-aim at the best open class immediately. Marks spent defending a reachable Second Upper are worth more than marks spent mourning a First that arithmetic has already taken.
