Quiz # 2 Total Questions : 10
Please read the following instructions carefully!
Quiz will be based upon Multiple Choice Questions (MCQs).
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 VULMS.
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 / Backspace Button while attempting a question, otherwise you will lose that question.
DO NOT refresh the page unnecessarily, specially when following messages appear
Question Timeout: Now loading next question…
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 question next to the last shown question. 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.
