INTRODUCTION:
This project is about ONLINE QUIZ SYSTEM which provides the facility to both Teachers and Students. Teachers have a separate
login system to generate quiz according to subject. A program has a facility to Insert questions in quiz along with different
functionalities like update quiz, view quiz, select quiz and delete quiz. There is also a separate Administrative Login provided to
teachers so that students can’t cheat by entering into teacher’s login and getting the quizzes. Students have separate section for login,
and take quiz. After taking quizzes the program will check the quizzes, generate marks and view reports.
For entering into whole process there is a system of Login where students and teachers give their ID and password. If there is a new
user in process the program also have a facility to register a new student. Besides that system also checks either password is accurate
or not and it does also provides facility to recover password in case of loose your password and to change the existing password.
Along with all this, there are different types of exception handling, security and search modules are made to make the program more
convenient and user friendly.
