Level
3- Highly Addressed, Level 2-Moderately Addressed, Level 1-Low Addressed. Method
is to relate the level of PO with the number of hours devoted to the COs
which address the given PO. If >40% of classroom sessions addressing a
particular PO, it is considered that PO is addressed at Level 3 If 25 to 40% of
classroom sessions addressing a particular PO, it is considered that PO is
addressed at Level 2 If 5 to 25% of classroom sessions addressing a
particular PO, it is considered that PO is addressed at Level 1 If < 5% of
classroom sessions addressing a particular PO, it is considered that PO is
considered not-addressed. |

LIST OF GRADED PRACTICAL EXERCISES
The practical/Graded exercises should be properly designed and
implemented with an attempt to develop different types of learning out comes in
affective domain and psychomotor domain, so that students are able to acquire
the necessary skills. Following is the list of experiments to be carried out.
