NITIE Mumbai happens to be my brother’s alma mater, so I think I can give you an idea about life at the institute.
Aside from that, two to three classes each day are required. Prepare for case studies and try to pass at least one for a bonus point on your CV (takes most of the time). Focus on your final results rather than doing 4-5 assignments (one assignment is enough).
NITIE has a beautiful pond and a lush green campus. Students usually enjoy the beauty of the campus in between classes, and they occasionally visit the pond after dinner.
Outside campus, like any other institution in India, there is a small corner shop called KASHI Snacks. From tea to food, this restaurant has everything for NITIE students. As a result, this is a site that is generally crowded with students.
