How to Calculate Your Final Grade (SA University Guide)

If your semester marks feel confusing, use one formula:

Final Grade = Σ(Assessment % × Weight)

Worked example

You have:

• Test: 68% (weight 25%)
• Assignment: 75% (weight 25%)
• Exam: 62% (weight 50%)

Calculation:

• 68 × 0.25 = 17.0
• 75 × 0.25 = 18.75
• 62 × 0.50 = 31.0

Final = 66.75%

Common mistakes

• Mixing percentages and decimals.
• Ignoring weight values from your module outline.
• Estimating without checking whether marks are out of 50, 100, or another total.

FAQ

Do all modules use the same weighting?

No. Always check your module guide; some split continuous assessment and final exam differently.

Calculate using exact values first, then compare with your faculty's rounding rules.
