study btech at anna university then mtech at IIT or btech at IIT ...? which is better for future?
When both are concerned IIT has great exposure and reputation than Anna University.
IIT is a dream college for todays Engineering aspirants. To get into IIT you should have a valid score in JEE Advanced examination.
To get into Anna university you should apply for TNEA(Tamil Nadu Engineering Admissions). There is no entrance exams till now for joining Anna University and its affiliated institutions.
IIT has good research facilities and a great place to learn. Faculty and students will be from all over the country and you will adapt yourself to become a Top Engineer in the world.
So doing b-tech at IIT is far more better than doing b-tech from Anna University and then pursuing Mtech from IIT.
Thank you.
Hope it helps you.
