Hello Karan Garg,

BITSAT is basically an entrance examination conducted by the Birla Institute of Technology, for admission to its campuses in UG courses. The branches are engineering ones, like Computer Science, Information Technology, Mechanical, Electrical, Electrical and Electronics, and so on.

Artificial Inteliigence is not a specific engineering branch, it is rather a particular subject that is being taught to the Information Technology and Computer Science related fields. If interested in AI, you may go for M.Tech in Artificial Intelligence from BITS.

Hope this Helps

Regards
