is cs complusary in 11 ,12 for pcm students?
If you want to study the course of Computer Science Engineering, then you need to compulsorily have PCM in your 10+2 course. The subject of computer science isn't compulsorily. So even if you don't have CS in your 10+2 but you are a PCM student, then also you are eligible for the course of BTech Computer Science Engineering.
