How strict is IMT Hyderabad with regard to students staying in a hostel?

During your PGDM, your life will become extremely busy and also very challenging at times. You will become busy with classes, pre and post-class assignments, extracurricular activities, club activities, etc. You will have no time left to do anything else 

that you may have planned for your hostel life. You will end up spending your free time catching up on some sleep or going for a walk/jog on the 30-acre lush green IMT Hyderabad campus.

The same holds for all the other top business schools and not just IMT Hyderabad.

Therefore, stop worrying about the IMT Hyderabad hostel's strictness and rules. You will become so involved in your PGDM that you won't get enough time to ponder these small issues.
