You can do the Integrated BTech-MTech course after 10+2 but not directly MTech. Now if you wish to go for the Integrated MTech course, then why will you go again abroad for the Masters course?. See if you wish to go for the Masters abroad, then my suggestion for you will be to go for the BTech course and not the BTech-MTech after MTech again going for the Masters abroad, its nothing but a misuse of resources.

The fields which you can go for the BTech course in VIT are provided below:

B.Tech Artificial Intelligence and Robotics

B.Tech Artificial Intelligence and Machine Learning

B.Tech Electronics and Computer Engineering

B.Tech Computer Science Engineering and Business Systems

B.Tech Computer Science and Engineering with Specialization in Data Science

B.Tech Civil Engineering

B.Tech Computer Science and Engineering with Specialization in Information Security

B.Tech Computer Science and Engineering Specialization in Internet of Things
