This is not necessary that you should have pcm to get computer science. If you have studied computer science in the board exam then you can choose du bsc computer science course and able to work as a computer programmer like engineer. Also you can choose diploma courses in computer science and or you may do msc in computer science. But dont forget to choose computer science in your studies if their is any option.

Hello

Even if you have PCB you can give all the exams but there you have to write PCM and then if you qualify in those exams like jee,cet,comedk etc and few Engineering collges have their own exam so if you can clear there exam you can get a seat in computer science engineering then you can become a software engineer.

Thank you.
