Hello candidate !!

First of all , congratulations for your marks that you obtained in your class 12th. As per your mentioned query , see you cannot get the admission in btech from the pcb group. As PCB stands for physics, chemistry and biology but in btech you have to be mathematics subject in your class 12th. From PCB group you can go for medical sector. So you can get admission in btech from pcm group.

I hope you are clear now.

Good luck !!
