6th ACTIVITY

3 Days college workshop

The third workshop for college was held from 29^th Sept 2022 to 01^st Oct 2022 in which 11 students of Jawaharlal Institute of Technology, Borawan participated.

These students were from different departments. In this batch there were 02 students from Mechanical branch, 06 students of Electrical branch, 03 students of Electronic branch.

We made two groups of students.

It was a three day workshop. In this, on the first day, information about the machines were given to the students and all the software related to it were taught to the students.
