The document describes a project that provides online quizzes to test knowledge on various topics using database connectivity. It includes source code for login, registration, menu selection, quiz questions, and results display screens. The project uses Java Swing for the front-end and MySQL database to store user details, questions, answers, and test performance. It allows users to register, select a subject to test, attempt questions, view results, and retake tests.

WORKING DESCRIPTION
OF PROJECT
The purpose of this project is to provide
a system that provides quizzes to test
your knowledge on various topics. This
project USES DATABASE
CONNECTIVITY to store details of
registered candidates, question and
answers and the test-performance details
in a MySQL database.
Technology used
 Frond End : Java Swing
 Back End : MySQL
