The Vision.

Traditional exam systems are fragmented. Syllabus tracking lives somewhere, tests are handled elsewhere, and ranking is calculated manually. VLE centralizes everything into one performance-driven academic infrastructure.

It is not just an online test portal; it is a full-scale digital academic evaluation system designed for performance tracking, ranking intelligence, and scalable exam management.

Syllabus Engine

Admins define structured syllabus hierarchy, map topics to exams, and track coverage percentage. This creates measurable academic coverage.

  • Hierarchy Definition
  • Topic to Exam Mapping
  • Coverage Tracking

Exam Engine

Supports timed exams, section-based questions, and negative marking logic. Session integrity is strictly maintained server-side.

  • Secure Session Lock
  • Sectional Questions
  • Auto Submission Logic

Ranking Engine.

Python Evaluation Layer

Python handles the heavy statistical lifting. Percentile distribution, normalization logic, and tie-breaking rules ensure accurate ranking even with massive student volumes.
