I’m ready to license an existing browser-based online testing system that I can start using right away—no custom build from scratch. My must-haves are: • Web interface that works smoothly on desktop browsers, with separate admin and candidate dashboards. • Robust multiple-choice question (MCQ) engine with timed exams, automatic scoring, result analytics, and downloadable reports. • Central question bank, test scheduling, basic security, login system, and role-based permissions. • White-label / self-hosted deployment with full rebranding—logo, colors, wording, even URL and email templates. • Optional extras (nice to have): descriptive question support, webcam or screen-share proctoring, anti-cheating measures. Please include in your reply: 1. Public or credentialed demo link. 2. Feature list highlighting everything above. 3. One-time or subscription pricing, plus licensing terms (user limits, update policy, source access). 4. Typical deployment requirements and turnaround time. I’m ready to proceed immediately with the best ready-made solution, so showcase what you already have rather than proposing new development.
