Rules & Sources

Every number OpenCGPA uses comes from a document published by the institution itself. This page lists those documents, how we check them, and what has changed.

How a rule gets published

01
Collect

We download the regulation, scheme of teaching, prospectus or circular from the institution's own website and keep a hash-pinned copy.

02
Transcribe

Grade tables, credits, weights and formulas are copied from that saved copy, with the page and the exact lines they came from.

03
Cross-check

A second pass checks every value against the saved document before it can be published.

04
Publish

The rule set gets a version and a verification date, shown on every calculator. Unchecked rules are never shown.

Source register

329 published rule sets from 619 official documents. Each row links to the document behind it.

Each document is saved when we capture it; the register shows the publisher's own link. Retrieval dates: 2 Oct 2026.
