I need a straightforward web-based quiz platform that lets me: • create unlimited quizzes from an admin panel, each containing Multiple Correct Questions, Single Correct Questions, Short/Integer (number) answers, and attach images or bilingual (Hindi/English) text to both questions and options; • assign custom marks and negative marks per question type; • generate individual user accounts so participants can log in and attempt any quiz I activate for them; • hold all scores until I decide to release them, then show full results, rankings, and an automatic “winner” list only After a review period. A clean dashboard for both admin and users is enough for now—no need for fancy graphics; the focus is on reliable question management, secure user authentication, and accurate scoring logic. Please build it with a commonly supported tech stack (PHP-MySQL, Node-Mongo, or similar) so I can host it on standard shared hosting later. Basic mobile responsiveness and clear documentation on how to add quizzes, release results, and export data will complete the job.
