B.A

Hi,
You can go for any arts subject after completing class 12th from science stream. You can check the eligibility criteria for universities as they may either have entrance or on the basis of merit. If you plan to apply for DU, a deduction of 2.5% is done from your aggregate percentage, if you are changing your stream.

Not necessarily BA in economics required. Graduate from any disciplines with 50% or more may apply for MA in economics.

Yes, most of the universities require minimum 50% marks in 12th class and you need to appear for entrance exam and interview as per admission process of the particular university in which you want to apply.

M.Sc psychology (clinical or HRDM) / MBA will be a better choice.

Hi,
It's very admirable that you are interested about pursuing economics but sadly without mathematics it's not possible to get a Bachelor's degree in economics as maths is an integral part of the mentioned subject.
Don't lose hope, there are some awesome subjects you can pursue after 12th.
