CA

The main difference between CA CS studies is that in CS, you are going to learn more about company law and in CA, you are going to learn more about accounting and taxation.

Hi Harman,
It completely depends on the university. Some universities consider CA article ship as work experience while some do not. Also, if you are doing MS and not MBA, you need not to worry about work experience as only MBA programmes require work experience. Please get in touch with the universities for university specific admission requirements.

Obviously, a CA is superior in every corner as compared to an MBA graduate.
In terms of knowledge and experience, an MBA graduate comes no where near to a CA.
Only thing is that MBA graduate will possess good communication skills.
That's all.

Yes, you can, but you need to work very hard. You need to have a clear understanding of class 11th and 12th concepts. You need to qualify CPT exam followed by IPCC. Join a good coaching institute to score good marks in CPT exam. You should have a good command over accountancy too.

Yes, however, I would advise you to do CA while doing graduation only. Also, BA and CA is rare and not so sought or favorable combination. Instead, you should do CA and B.Com in accounts and finance or B.Com in financial accounting specially designed for CA by the University of Madras and IGNOU
If you still want to do BA economics, then prefer CFA or CS.

If you want to do CA then apply for CPT and clear your CPT and while doing CA, you can do B.Com form any college. If you are doing external .Com, it will help you for doing CA.

Yes, science students could easily pursue for CA .
You can appear for CPT exam. There is no age limit, no minimum or maximum attempts.
Every day, you have to practice 3 hours Accounts and maths.

Yes, you can. Also, have a look at VGU-Jaipur and Chandigarh University.
