Accounting & Commerce

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.

Dear,
You need to check the new guidelines of DU SOL for reappear for 1 subject after many years as they have changed many rules.
All the best.

After 12th, you have options of doing BCS and side by side, start learning computer language like java, c+, etc.

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.

As per the university, you can be promoted only when you pass in 4 subjects of final year B.Com.

Yes, CS is a very good option for you but in CS you are going to study company law so think before choosing a course among CS, CA and CMA.

Dear Pradyuman,
As a career adviser, I can't say one course is better than the other. Both courses have its own merits.
B.Com and BBA are courses with similar subjects. Both are related with business / commerce. B.Com is a traditional course where as BBA is new age course.
There are lot of employment opportunities in Finance, Accounting, Sales, Marketing , Banking , Insurance etc. B Com (Taxation) graduates can practice independently as Tax Practitioner.

Dear,
According to me, you should invest your money for MBA in Australia and do your Bachelor's degree as B.Com (Honors), economics (Honors) or BBA from India.
All the Best
