"Introduction Class" for II Sem. 'A'

Dear students,

Hearty welcome to second semester of your engineering course.

Be positive.

Everyday is a new opportunity for us to re-correct our yesterday's mistake to move ahead to reach our destiny.

Be inspired. Inspire others.

Read for knowledge.

Once, you gain knowledge apply it. (Then, value will come for the knowledge.)

Be regular to classes. You need to give APPLICATION for yours every ABSENT to classes with genuine reason. It is mandatory.

Listen to all teachers.

Give respect to all teachers.

Wish the teachers, when they come in front of you.

Wear Formal dress with smiling face.

Be healthy with good thoughts in your mind.

Ours beauty depends upon our good thoughts.


Our institute has one vision to provide Efficient Engineers to deal with the societal technical problems.

To convert this dream in to reality, our institute has Institute Mission. (Action to convert Institute Vision in to reality)

As a part of Institute Vision and Institute Mission, all departments in our college has individual Department Vision and Department Mission.

Programme means: to which branch, you have taken admission.
i.e. Computer Science and Engineering is a Program.

We have Program Educational Objectives (PEOs), as well as Program Outcomes (POs)

As a part of Department Mission, all teachers are teaching subjects(courses) with some objective, which are called Course Learning Objectives.

All our Institute Vision and Institute Mission, Department Vision and Department Vision are working fine to make your Family Vision and Family Mission successful. i.e. to convert yours dreams into reality.

Our college is accredited by NBA, NAAC and ISO. i.e. to provide Outcome Based Education(OBE) to you....So, be happy...be inspired...recall yours dreams and work...listen to all teachers. We are here, we are working for you to convert your dream in to reality. (Indirectly our dream will be converted into reality).
