Dear Student,

This is the atmosphere document by which we are trying to show you the approximate scenario in the viva room.
Note : This is one of its kind yet, the complete booklet/white paper of viva preparation we will publish very soon.
Viva-Voice, It is not just the presentation of your project but also the representation of your professional skills. We will provide you detailed study(in the form of questioner asked by different professors) on various viva-voices conducted, which will help you to face viva and score more in your final year project report.
A Person who is taking your viva-voice is completely depends on your explanation about your project means he/she does not do any home work for taking your viva. They start studying your project just before 10 minutes of your viva. If your report has some problem related to index, content, coding don't worry about that you can remove it just by showing confidence and doing professional talk in front of your professor.

=> We can classify the all viva questions into four category viz.

1.     ABOUT PROJECT TITLE & PROJECT REPORTs
2.     ABOUT DOCUMENTATION i.e. THEORATICAL KNOWLEDGE
3.     ABOUT TESTING OF SOFTWARE AND
