Hi Deekshith,

An integrated M.Tech gives you 3 years of under graduation and 2 years of post graduation. The main advantage is that you wi be getting a dual degree with 1 year less of study. 

Another advantage is that, you get a deeper knowledge of the subject and also have better placement opportunities. This course needs more interest in the field of research. You might also get a stipend of 12k from Ministry of Human Resource Development in the final year.

All the best!
