Final Exam Requirement Projection Engine
This adaptive final grade projection module computes the minimum score needed on a remaining high‑impact assessment (final exam) to reach a specified overall course target. It models the course as a two-part weighted system: completed portion (locked performance) + pending terminal assessment (variable performance).
Core Formula
Required Final % = (Target% − Current% × (1 − FinalWeight)) ÷ FinalWeight Where FinalWeight is expressed as a decimal (e.g. 40% → 0.40).
Worked Scenario
- Current cumulative: 85%
- Final exam weight: 40% → remaining course weight = 0.40
- Desired overall: 90%
- Computation: (90 − 85 × 0.60) ÷ 0.40 = (90 − 51) ÷ 0.40 = 39 ÷ 0.40 = 97.50%
Interpretation Guidance
- < 50% required: Target already secured barring extreme under‑performance.
- 80–95% required: High precision study targeting needed; optimize weak domains.
- > 100% required: Mathematical impossibility—adjust expectation or pursue bonus credit (if allowed).
Strategic Tips
- Re-compute after late‑posted assignments to keep projections current.
- Simulate multiple desired outcomes (e.g. 88%, 90%, 92%) to set tiered goals.
- Track volatility: higher final weight → larger sensitivity to each projected score band.
FAQ Snapshot
- Why does it show >100%? Because current weighted average is below the trajectory needed; recovery no longer feasible without extra credit.
- Is rounding applied? Display rounds, but internal computation uses full floating precision.
