The curricula for all B.Tech. would include compulsory industrial training for 6 weeks carrying 2 credits to be carried
out in the summer vacation at end of the sixth semester.
The six-week industrial training undergone by the student in the summer vacation after the sixth semester would be
assessed within five weeks after commencement of the seventh semester. The students are required to submit a
report on the training received and give a seminar on the basis of which a grade would be awarded. The students are
also required to submit to Head of department a completion certificate in the prescribed form the competent authority
of the organization where the training was received without which he/she would not be assessed.
