Hey,

All three colleges mentioned are good, but BIT Jaipur should be the first priority for CSE branch because of its high ratings and reviews. Symbiosis Institute of Technology must be your last preferrence among three. 

 High rank of BIT Jaipur college than the above mentioned, good infastructure, high packages and the tag BIT is always being a good addition.If you are a person living in Pune or Patna and prefer staying in our city than SIT Pune and BIT Patna are still great choices.

Try avoiding the other RTU college for B.Tech, the BIT syllabus is just smilar to what it is in IIT's. Overall BIT Jaipur stand high among the rest.

Thanks!
