Dear Students,
You are informed that Quiz no.3 will be started according to the following schedule;
Opening Date and Time of Quiz January 27, 2014 at 12:01AM
Closing Date and Time of Quiz January 28, 2014 at 11:59PM
Instructions:
Read the following instructions carefully before attempting the Quiz No.3.
• Quiz will be based upon Multiple Choice Questions (MCQs) and it will cover Lesson nos. 21 to Lesson nos. 30.
• You can start attempting the quiz any time within given date(s) and time of a particular subject by clicking the link for Quiz in LMS.
• Each question has a fixed time of 90 seconds. So you have to save your answer before 90 seconds. But due to unstable internet speeds, it is recommended that you should save your answer within 60 seconds. While attempting a question, keep an eye on the remaining time.
• Attempting quiz is unidirectional. Once you move forward to the next question, you can not go back to the previous one. Therefore before moving to the next question, make sure that you have selected the best option.
• DO NOT press back button while attempting a question; otherwise you will lose a question.
• DO NOT refresh the page unnecessarily.
• DO NOT try to disable “JavaScript” in your browser; otherwise you will not be able to attempt the quiz.
• If for any reason, you lose access to internet (like power failure or disconnection of internet); you will be able to attempt the quiz again from the position where you left in last attempt. But remember that you have to complete the quiz before expiry of the deadline
Solved Quiz No.3 enjoy.
