This is a question that I faced by many puzzled friends and reluctant family. I believe that studying abroad is all about questioning inner cultural perceptions and starting adult life with a perspective outside the home bubble. That perspective really smacks the face of Indian newcomers, with chaotic traffic, fiery food, dangerously-relaxed departments, and living in one culture surrounded by infinite others.
India is known for their diversity, but some challenges are universal. Although that is exactly the point, it is a challenge. Students are well supported and are given as many amenities as possible, but at the end of the day, a program like BCA Chennai builds character and resolve, while giving students an opportunity to live in the most chaotically-functional diverse democracy on the planet.
However bleak the day may look, a handful of Dosa bread and a tumbler of Chai can fix just about anything.
