What kind of difficulties for north Indian students will come in IIT Madras or IIT Hyderabad or IIT Hyderabad?

My friend hails from Mumbai and was a student in IIT Madras. She claimed that the weather in Chennai is always hot and humid which can be very frustrating at times. But after a few months, you get used to it and it is not that big of an inconvenience.

IIT Madras has both south as well as north Indian messes so students rarely face any issues regarding it. A number of canteens are there that provide food satisfying taste buds in every corner of the country.

Locals in Chennai cannot speak Hindi and you will find most of them talking either in Tamil or broken English, locals don't speak Hindi. So the language barrier might be a bit troublesome especially when you are out and want to explore. It’s advisable to learn some basic Tamil. 

Although IIT Madras welcomes a mixed bag of students, the majority comprises South Indians. However, there is no bias in academics toward South Indians at IIT Madras. 

All in all, I refuse to believe that the institute is partial toward South Indians. In fact, you will find many friendly South Indians here at IIT Madras.
