PRACTICALS

Section A

      Students are expected to perform four experiments in all from which they will have to perform one experiment in the semester end exam.

                 The distribution of marks in the practical examination will be as follows:

1.              One experiment                               :  30 marks.

             Distribution of marks will be as follows:

·      Figure / Formula/Theory           :         7

·      Observation / Calculation          :        16

·      Result /Result Analysis              :       5

·      Precautions                                :        2

2.         Viva –Voce                                      :         5 marks

                   Total                                               :        35 marks

Section B

                  Project                                             :           35 marks

                 Distribution of marks will be as follows:

·      Seminar presentation                   :             15

·      Write up                                       :             10

·      Viva –voce                                   :             10

List of Experiments    

Section – A

Section – B

1.         Project

     Details of Project

Students of semester IV are required to choose a topic for the project from a list approved by the department. They are required to perform a new experiment or carry out studies for writing a review article on a subject. At the end of the semester, a project report shall be submitted by each student. This project will be assigned to them in the beginning of the IV semester.

Evaluation of Project:

A mid term evaluation of the project will be made along with the second CA test. This will carry 30 % of the total marks assigned for the project. At the end of the semester, the student shall be examined on the basis of project report submitted by her by a panel of external and internal examiners. The external appointed for the practical exam shall also evaluate the project along with the internal project supervisors. The evaluation of project will be based on presentation / viva-voce.

Total duration of practical exam and project evaluation shall be 5 hours.
