BA is useless and it would not be helpful for css , further studies or any job.

English is important in css but not English literature. You should do 4 years BS from good university, if you have an option. Otherwise BSc is the right option. Take subjects of your choice and also figure out your subject of interest , which you would select for your masters degree.
Doing BA while hoping to clear css, is not a wise decision at all. For css, you may opt the subjects, which you will study in Bsc .
