Both IIT Hyderabad and IIT Madras are well-recognized institutions in India. However, opting for Computer Science at IIT Hyderabad or Mechanical at IIT Madras completely depends on your choice, interest, and career goals.
In my opinion, the first and foremost step of choosing an institute is to determine which branch you are inclined towards. You can choose the right Institute only after you know which branch you will be taking. To help you in the same, I have mentioned the core topics covered in both CS and Mechanical.
CSE
Mechanical engineering
These are some of the topics that you already covered in school and will cover their advanced levels in these 2 fields. You will also learn the application of these concepts.
It’s important to note that the list of topics mentioned is just for reference and not exhaustive.
