Architecture Built for High Scalability & Reliability
Engineered from the database engine up to prevent client tampering, timer manipulation, and network dropouts.
Authoritative Server Timer
Expirations are calculated strictly on the backend. Browser refreshes, timezone changes, or tab closures cannot grant extra time.
Real-Time Answer Sync
Every selection is immediately saved asynchronously to the database. Complete test progress survives reloads and network reconnects.
HttpOnly Cookie Auth
Access tokens are stored inside secure, HTTP-only SameSite cookies, completely inaccessible to malicious JavaScript or XSS vectors.
Bulk Question Importer
Import question papers in bulk from CSV, XLSX, or JSON formats with automated validation preview before final database commit.
Configurable Scoring Models
Support for custom positive marks, negative deductions, passing thresholds, question limits, and comprehensive result exports.
Auto-Submission Engine
Attempts automatically freeze and finalize the moment timer expires, computing exact scores and preventing post-deadline modifications.
From Blueprinting to Live Proctoring & Real-Time Grading
SuperTet streamlines the end-to-end examination pipeline with dedicated interfaces designed specifically for administrators, faculty, and candidates.
Test Blueprint & Import
Admins configure duration, passing marks, negative penalty ratios, and import 100+ questions in seconds via CSV/Excel.
Live Distraction-Free Exam
Candidates test in a dedicated room featuring a 5-state color-coded Question Palette and instant asynchronous answer auto-save.
Authoritative Auto-Submit
Server-side timers strictly enforce submission upon expiration. Zero overtime grace or clock manipulation vulnerabilities.
Diagnostics & CSV Audits
Immediate scorecards, accuracy rates, and question-by-question explanations for candidates, plus 1-click export for faculty.
Question 7 of 20
Which of the following database isolation levels completely prevents dirty reads, non-repeatable reads, and phantom reads in high-concurrency enterprise workloads?
Question Palette (20)
InteractiveEngineered to Surpass Legacy Assessment Systems

Atomic answer synchronization on every single choice selection.
Zero client device clock drift or overtime grace tampering.
High-throughput async DB writes with SQLAlchemy 2.0.
Scalable containerized deployment with PostgreSQL pooling.
Architectural Breakdown: SuperTet vs Legacy Testing Platforms
| Feature Dimension | Legacy Online Testing | SuperTet Enterprise Platform |
|---|---|---|
| Exam Timer Control | Client-side JavaScript timers (Vulnerable to OS clock changes & page refresh manipulation) | Backend Authoritative Expiry (Absolute UTC timestamps) |
| Network Loss & Crash Recovery | Answers stored in browser cache; lost permanently if browser crashes or session terminates | Instant Atomic Sync to DB on every option selection |
| Authentication Security | JWT stored in LocalStorage (Prone to Cross-Site Scripting XSS token extraction) | HttpOnly SameSite Strict/Lax Protected Cookies |
| Question Importing | Manual single question entry forms prone to human copy-paste errors | Bulk CSV, Excel (.xlsx), & JSON parser with pre-validation |
