If one misses the GTU external viva then what happens?
There are nearly 120 students in a batch. Sometimes, it happens that the Vivas are conducted for 2 days for a particular subject. So the batch is divided into two groups : Group A on first day and Group B on second day.
Suppose you are in Group A and you have Viva on the first day. Due to some reason you come to know that you will not be able to give your Viva on that day. You must inform your HOD about your valid excuse. He will talk with the External faculty and request him to take your Viva the next day with the Group B.
But if you fail to give the Viva with the Group B then you'll surely have to suffer the consequences. You'll get backlog in that particular subject and you'll need to clear it in the upcoming semester.
