What Is the Diploma / Poly SGPA Calculator?
Official grading rules, credit system, statutory ordinances, and semester performance guidelines for Diploma in Engineering / Technology (Polytechnic):
The Diploma / Poly SGPA Calculator by Result91 is a dedicated academic tool engineered specifically for students pursuing Diploma in Engineering / Technology (Polytechnic) (Diploma / Poly) across autonomous institutes and universities under State Boards of Technical Education (MSBTE, DTE, SBTE, BTEUP, WBSCTE).
In compliance with Choice Based Credit System (CBCS) model curricula, this calculator enables students to compute their exact Semester Grade Point Average (SGPA), total quality points (Σ Ci × Gi), required course credits, equivalent percentage (Percentage (%) = SGPA × 10 (or State Board Formula)), and academic honors standing.
Official Regulations & Statutory Source
Grading benchmarks, credit multipliers, and curriculum calculations on this page are strictly derived from official statutory examination guidelines approved by State Boards of Technical Education (MSBTE, DTE, SBTE, BTEUP, WBSCTE).
Prescribed under standard Choice Based Credit System (CBCS) guidelines of State Boards of Technical Education (MSBTE, DTE, SBTE, BTEUP, WBSCTE). Verified against national higher education ordinances for semester grade cards and degree transcripts.
Diploma / Poly SGPA Formula
Under State Boards of Technical Education (MSBTE, DTE, SBTE, BTEUP, WBSCTE), Semester Grade Point Average is calculated as the credit-weighted arithmetic average of grade points:
Σ Cᵢ
Where Cᵢ = Course Credits, Gᵢ = Numerical Grade Points
Academic workload allocated to each theory course, lab practical, or elective in Diploma / Poly.
Numerical score mapped to earned letter grades on the official 10-point scale (O=10, A+=9, A=8, B+=7).
Product of credit hours and grade points. Summing all quality points and dividing by total semester credits yields official SGPA.
