arts vs engineering
Both Arts and Engineering are best at their places. You cannot compare both of them, because both are entirely different streams. So, Both courses have scope for students. As, Arts provides scope to students at its level and Engineering at its level. One who wants to go for government jobs can pursue arts courses and one who wants to get employed in a technical field, then he/she can go for engineering stream.
All the three stream have different scope which are equally important . Science stream can help you become a doctor , engineer , scientist , so on. Commerce stream offers you a variety career related money & economy like RBI , banking , CA , CS etc. Choose only the subject you like the most .
It's not about the scope. It's all about the skills. You will find more engineers doing preparation for Banking exams or SSC or UPSC. And some guys from arts background are doing work of Engineers. I know a lot of people doing digital Marketing and other things which are directly related to IT engineers.
Just develop your skills. If you are thinking to go in IT then make sure you have possession of at least one specific Programming Language. That will be more than good.
