Dear aspirant !

Hope you are doing well! If I am not wrong then you mistyped it bhed ,it should be b.ed ,,if talk about bed then yes anyone from any stream , no matter , whether it is arts, commerce or science,being a science student ,you can pursue bed after your graduation ,do bsc first and then go for bed.

For more information about bed ,visit the link;-
