For Bsc - Computer Science is PCM required ? or PCB is ok ?
For most of the colleges, if you wish to get BSc CS then you need to have Mathematics in 10+2. PCB students won't be eligible if they don't have Mathematics. Now if your college allows you then its a different case, but in general most colleges ask for Physics and Mathematics in 10+2 in order to be eligible for BSc CS.
