PRACTICALS

The record, to be submitted by the students, at the time of their annual examination, has to include:

• Record of at least 8 Experiments [with 4 from each section], to be performed by the students.
• Record of at least 6 Activities [with 3 each from section A and section B], to be performed by the students.
• Report of the project carried out by the students.

SECTION A

Experiments
