Hey,

First and foremost I would like to inform you that you can't pursue Bsc (CT) as your background in class 12th is Arts. You can only opt for science courses if you have ready science related subjects in your 10+2 classes.

Rest as far as your second part of question is concerned I am answering it independently from the first part of the question.

Yes it is a correct field. Both Computer Technology as well as MBA are job oriented and current job trends people should pursue in order to gain a stability in their life. Theses courses will help you earn more money and they will shape your personality as per the current job profile.

Hope that helps.

Thank you
