Quiz No. 2Dated:Jan 29, 20

Dear Students,

 

As you know that VU has initiated online quiz system. Therefore your Quiz # 02 of CS614 (Data Warehousing) for your Final term exam preparation will be held on February 06, 2020 (Thursday) to February 07, 2020 (Friday) (Quiz open for Two days) containing Lessons from Lecture # 23 to Lecture # 40.

 

Read the following instructions carefully before attempting the Quiz.

 

Quiz will be based upon Multiple Choice Questions.

You have to attempt the quiz online. You can start attempting the quiz any time within given date(s) of a particular subject by clicking the link for Quiz in LMS.

 

The time to attempt the Quiz is limited. Once you login to attempt the quiz, the countdown will start and you have to complete the quiz in given amount of time. So always keep an eye on the remaining time.

 

Attempting quiz is unidirectional. Once you move forward to the next question, you can not come back to the previous one. Therefore before moving to the next question, make sure that you have selected the best option.

 

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.

 

If any student failed to attempt the quiz in given time then no re-take or offline quiz will be held.

 

Best of Luck!
