5. Student’s feedback:-
Industrial visit to B.E.S.T workshop was organized by Mechanical engineering department of MHSSCOE for
Final Year Students.
The guiding staff on site was very supportive to all students.
We are sure that this visit will help us in our future practical life and bring a positive change in our thinking and
practical behavior regarding Education and specially Engineering.
We, the Students of Final Year Mechanical Engineering are extremely thankful to Hon. D.S Talwai, HOD of
Mechanical Engineering for the permission.
We would like to specially thank Prof. Bhaskar Gardas & Prof. A.H Jagtap, Chief Coordinators of this
industrial visit and all staff & student coordinators for providing a full-fledged support in all aspects during the
