How is life of a CS student in NSIT and DTU as compared with life of a CS student in an IIT?

Here are a few points of differences between the life of a CS student in NSUT/Delhi and life of a CS student in an IIT

• Academic Workload: The first-year students in NSUT and DTU have a laid-back and relaxed experience with no academic pressure of completing assignments, preparing for internals, performing practicals, etc. Whereas IITians are busy with a hectic schedule and rigorous academics right from the first year. They have to be serious about their practicals, labs, and assignments.
• Attendance Policy: Although NSUT and DTU have a 75% attendance policy NSUT students don’t follow and the consequences aren’t very serious. IITs on the other hand are very serious about attendance policies. Students need to attend classes, tutorials, and labs each requiring 75% attendance.
• Curriculum: NSUT and DTU have a relatively lighter and easier curriculum than IITs which have a very rigorous and challenging course syllabus. 
• Campus life: NSUT and DTU have relatively dull campus life than IITs. Students are not involved in organizing summits, seminars, presentations, events, etc. While in IITs the campus is buzzing with some or other activities every day. 
• Hostel life: Unfortunately in India, the quality of hostel life depends on your gender. If you are a girl you will have a full life anywhere whereas if you are a boy you will get full freedom at either place.
• Placements: Placements won’t be an issue if you are a CSE graduate because both NSUT and IITs offer similar opportunities.

Hope the comparison helps you get a better understanding of lives in different colleges.
