In the practical examination along with experiments you have to face viva
voce from the internal / external examiner. It is just to know your depth of
knowledge and understanding of the given experiment / project work. Based
on your performance you will be credited with the deserving score.
As CBSE releases the date sheet, students get engrossed mostly in
preparing for the theoretical examinations. As a result, most of the students
skip preparing for their practical examination which is also important part for
grabbing overall a good score. In each of these subjects Physics, Chemistry and
Biology 30 per cent marks is reserved for their Practical Examinations. That
means out of 100 total marks, 30 marks is allotted for Practical Examination.
And out the 30 marks of Practical, generally 5-7 marks is kept for viva voce.
Syllabus for Class 12 Physics and Chemical Practical Examinations
Evaluation scheme Maximum Marks: 30 (Total 30 marks for each Physics and
Chemistry)
- 2 Experiments containing 8 marks each (one from
each section, total = 16 marks)
- Practical Record = 6 marks
- Project Work = 3 marks
- Viva on Experiments and Project Work = 5 marks
Syllabus for Class 12 Biology Practical Examination
Evaluation scheme Maximum Marks: 30 (Total 30 marks)
- One major experiment 5
- One minor experiment 4
- Slide preparation 5
- Spotting 7
- Practical record + viva voce 4
- Project record + viva voce 5
The questions asked as well as the circumstance in which a student faces
viva voce are different from the theoretical examination so it is always better
to prepare for viva voce separately. A student with some prior preparation for
viva is definitely going to give him or her more confidence. Besides knowledge,
confidence level and body language also play an important role while facing the
external taking viva examination.
Types of Questions asked in Class 12 Viva Voce
Methodology and Principles are frequently asked questions in viva voce hence;
you should know the basics of the experiment. There might be the some of the questions
based on the experiment you are asked to perform like how the slope is
calculated, what is the aim of experiment, what are apparatus required, what
are the precautions that need to be taken into account, etc. You should be able
to explain how you performed the experiment. How you took the readings. Another
important question is about the least count of the measuring instrument.
The level
and variety of questions asked in viva voce depends solely on the concerned
teacher and the type of experiment given to you and so, there can be plethoras
of questions in subjects.
