Hello,


I would say you should go for MBA, as it will be a simple 2 years course where you will learn everything in college under professors but if you will choose to go for CA then get ready for devoting atleast 15 hours in a day as everything will be new to you so you will have to give more and more time.CA exams are very tough and success rate in those exams is also less.
Be prepared to give time for at least 4 years.this is reality.Think wisely before choosing a career.

I hope this helps.
