Institutional LMS :: Concurrent Exam Submissions & Real-Time Grading Engine

/ ARCHITECTURAL OVERVIEW

The Challenge: Handling 15,000 Simultaneous Exam Submissions

Academic institutions and national certification boards experience massive traffic spikes during timed online examinations. When 15,000 students submit their exam papers at 11:59 AM simultaneously, standard database architectures crash under the write contention. The institution needed an ultra-resilient exam engine with anti-cheating controls.

Core Architectural Capabilities

Redis Stream Ingestion Buffer

Buffers thousands of simultaneous exam submissions asynchronously, writing to relational storage without server timeouts.

Browser Tab-Switch Telemetry

Monitors window minimize, tab switching, and clipboard events in real time, automatically flagging academic dishonesty.

Automated MCQ & Formula Grading

Evaluates multiple-choice answers and numerical formulas instantly, calculating negative marking with zero human error.

Tamper-Proof QR Certificates

Generates digitally signed PDF transcripts and graduation certificates verifiable via public QR scanner.

Long-Term Guardian Custody Guaranteed

CareITLab does not deliver static files and abandon your organization. Every platform we build is backed by direct code-level guardianship, proactive security patching, and ongoing performance tuning under our strict SLA frameworks.
