Please read the following instructions carefully!

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.

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.
