You can get the information from above link. But I think you can't pursue ICWA because it had accounting terms which you are not familiar to as you are an arts student. So please check out the link for the reliable information for the same. Hope this helps.

If you are poor in study, then I am afraid you will not able to do any demanding course. Also, ICWA is not a valid course as far as I can tell. If you are asking about CA course then understand that it requires very hard work.

Hi Shubhanshi,
Registrations for the ICAI Foundation & Intermediate courses are open throughout the year. However, students willing to appear for June Term Examination should apply before 31st January of that year and for December Term Examination should apply before 31st July of that year.

Hi Pooja,
In order to work with public sector banks, you need to give certain exams. Topmost exams include IBPS Common Written Exam, SBI PO exam and NABARD exam. The age limit for all these exams is max 28 years.

Dear Gaurav,
Is it a wise choice or not depends on your future aspirations. If you want to make your career in accounting and taxation, then ICWA would be the good option. However, if you are looking for core finance career, then there are some other good options as well, like CFA or CFP, etc. So, it is all up to what you want to become.

Yes, after B.Com, you can go for intermediate stage. After that, you are going to do articleship for 6 months.

You don't need to take admission in ICWA. You need to register your name with Institute and you need to give their entrance that is CMA Foundation. After clearing your CMA Foundation, you need to register your name for CMA executive programme and after completing your executive program, you need to do articleship for 6 months and after completing it, you are going to get a chance for giving the final group of CMA.
