how much percentage in tenth is recqed for 11 pcb in cbse
Dear aspirant,
There is no official cut-off as such for getting into PCB stream. If you pass class 10 you should be able to pursue any stream of your choice. Some schools might have some cut-off as the PCB/PCM branches are highly preferred so they'll prefer offering it to students with better marks. Otherwise, there is no official cut-off, as long as you are interested, you can pursue it.
Hope this helps.
