NALSAR is situated nearly 35 km from Secunderabad city. The classes are conducted from 9 AM-5 PM every day. Apart from this, you can choose late hours for tutorials and projects. The seniors preferably choose late night timings.
Being a day scholar, you might be able to attend a few morning lectures some days after covering huge distances. However, it is difficult to be present for all of them as guest lectures happen on weekends usually.
One of my seniors was a local himself and he preferred to stay on the campus on weekdays. Going out can be hectic and you need permission from the warden. It will be tiresome for you to travel to the campus and back again at home. It will be practically impossible for you as a day scholar.
