I want to do Btech CS so kindly help me in my admissions in Btech CS by suggesting me good colleges where pcb students can do Btech CS

Have you tried parul university Gujarat? It is one of few colleges which is taking into account the new education policy which allows student from any background to do B.Tech. If you decide on anything please let me know because I am also thinking of something similar I am also a pcb student.

Sorry. But I think pcm is mandatory to pursue B.Tech in any branch.
