One of my friends studied at NUJS. According to her, hardships have varied reasons from academics to personal.

• The Cases/readings are worth easily 500 pages every day, preparing summaries/case briefs, Tutorials and then projects, presentations, vivas, and the tiring final semesters all comprise the academic hardships.
• Due to internships, you will miss your vacations. Internships are a temporary glimpse into what life will be like.
• After getting the grind to excel and to get placed / PPOs, some students suffer from existential crises, emotional upheavals, urge for infinite sabbaticals, etc. 
• The burden of studies and placements takes a toll on your personal life. 
• Case briefs become a reason for discord rather than unity. 
• The healthy competition suddenly gets replaced by a rat race. 

Lastly, all the things like hobbies, extra-curricular, etc. disappear. But even after all the hardships, it still is the best time of a student’s life at NLSIU.
