SGPA → CGPA Aggregation Framework – Multi‑Semester Performance Consolidation
This SGPA consolidation engine transforms discrete semester achievement vectors (SGPAs) into a unified cumulative grade point average (CGPA) for benchmarking, application dossiers, and longitudinal academic analytics.
Conversion Pathways
- Simple Mean: CGPA = (Σ SGPA) ÷ (# semesters) – assumes uniform credit load.
- Total Input Mode: Provide pre‑summed SGPA aggregate ÷ count for quick recompute.
- Weighted Credit Model: CGPA = Σ(SGPAᵢ × Creditsᵢ) ÷ Σ(Creditsᵢ) – accurate under varied credit intensity.
Illustrative Scenarios
Unweighted Example:
SGPAs: 8.0, 7.5, 8.5, 9.0 → Σ = 33.0 → 33 ÷ 4 = 8.25
Total Entry:
Aggregate 40.5 over 5 semesters → 40.5 ÷ 5 = 8.10
Weighted Credits:
(7.5×20) + (8.0×22) + (8.5×18) = 150 + 176 + 153 = 479; Total credits 60 → 479 ÷ 60 ≈ 7.98
Why This Matters
- Highlights trend acceleration or stagnation across academic phases.
- Supports eligibility checks for internships, honors pathways, and scholarships.
- Enables forward modeling: add projected SGPA to simulate future CGPA shifts.
