Is it compulsory to stay in the hostel at IIM Rohtak for all 5 years while doing IPM there? Also, do they have a rigid academic session where 90 attendance is compulsory?

Yes, IPM and the majority of other programs are offered entirely in residence on all IIM campuses.

For the purpose of clarification, the attendance policy is actually 100% mandatory (at least on paper). You must now obtain permission to miss classes and leave campus. Medical emergencies, urgent family functions, and so on are examples of exceptions.

Other rules that affect the daily lives of students are:

• Night curfews: First-year students are not permitted to leave their hostels after 10:30 p.m. Things become more relaxed as you advance in maturity level.
• Lights out time: During the first month, this is usually strictly enforced until you get acclimatized. The light-out time was mostly kept on paper then.
• Yoga: Yoga classes are required five days a week.
• Restriction: You can leave campus without permission only on Sundays; otherwise, a gate pass is required. Again, as you become senior, this becomes less strict.
• Discipline: Yes, there have been terminations based on disciplinary issues such as drinking, PDAs, and so on. As the other answer stated, you can't really escape.
