After searching a long time in internet I stumble upon 3 best websites to conduct online examination. There may be many websites but you will rarely get these types of free, user-friendly and ads free websites. If you are a teacher and want to conduct online exams for your students or if you are a student and want to appear some free quizzes  then this is the right place to learn about those websites.
