see this is some extra curricular activities and some of the college has mandatory rules for students to join some extra curricular activities to get the mandatory points as per the instruction of the university. however this extra curricular activities has no direct connection with the course structure or syllabus of any particular engineering course. you may go for any of it even if you are from mechanical or production engineering branch. extra curricular activities are same for all streams.
