Dear Aspirant

Hope you are doing well

It is totally depends on you on

According to me computer science will always remains at the top. Coming to the branch of petroleum engineering. I would personally suggest to go for it for masters not as a bachelors degree because, atleast in india the scope for this is pretty less. Almost 75 percent graduates from this stream are struggling to get the job in that sector. Since this sector is still in basic stage and is emerging , there are not many opportunities in this. So go for bachelors degree and you can take this for masters.

But if you wanted to know more about it check out the link given in below
