can I opt for btech course after 12th pcb..
The basic eligibility criteria to get admission in the btech course is that the candidate must have passed their 10+2 with physics, chemistry and mathematics as compulsory subjects, also candidate must have scored a total of 50% in their class 12th.
So if you were a PCB student in class 12th, then sorry but you are not eligible to pursue btech.
Hope this helps, all the best.
