Two types of  colleges  1) non autonomous college and 2)autonomous college

Hi Subham, There are a lot of autonomous college's in India and the college's may have either  B.Tech or B.E. The degree completely depends on the college. So please tell me the exact thing you want to know about these autonomous college's. Thank you

Hello,

I am for Birla Institute of Technology which is a deemed autonomous institute so I feel I am eligible to answer your query correctly. In BIT, the B.E. degree was provided upto the year 2018. From 2018 batch onwards, they have started providing courses under the B. Tech. degree. For different autonomous institutes in India, it is different but you would mostly get B. Tech. degrees in the majority of them. Hope this answer helps!
