CA Vs CPA
The Chartered Accountant course is conducted by the Institute of Chartered Accountants of India (ICAI) whereas CPA is an exam conducted by the American Institute of Certified Public Accountant (AICPA). CPA course requires anywhere from 7 months to 1 year to complete. On the other hand, you need to spend at least 4 to 5 years to complete your Chartered Accountant course. CA is a reputed qualification in India. It covers the Generally Accepted Accounting Principles prevalent in India, known as IND-AS. CA license holders have good career prospects in India. Comparatively, CPA is a global qualification that covers International Financial Reporting Standards (IFRS) and the Generally Accepted Accounting Principles in the US (USGAAP). CPA provides accounting professionals with a wide range of career opportunities in the US and various other major countries of the world especially in multi-national companies that originate or operate from the US soil. To take the CPA exam, you need to have a B.Com degree with 1st class or a B.Com degree along with a postgraduate degree. You can also appear for the exam if you have a B.Com degree and an Indian CA qualification. Further, you need to have at least one years experience of working in the Accounting and Finance industry to apply for a CPA license. For pursuing CA course, you need to take the Common Proficiency Test (CPT) after completing your senior secondary education, and there is no mandatory requirement of a degree. However, to apply for a CA license, one needs to have at least three years of article-ship experience in an accounting firm. CPA is an online exam with 4 sections which are Auditing and Attestation, Business Environment and Concepts, Financial Accounting and Reporting and Regulation. However, after you pass the first exam a time limit of 18 months applies to pass the other three exams. The CA has a three-stage exam process with 21 subjects overall. The first stage is the Common Proficiency Test which has 6 exams. Second stage is known as the Integrated Professional Competence Course with 7 exams and the third stage is Final examination which has 8 exams to clear. To clear each CPA exam, you need to score above the 75th Percentile to pass the exam. On the other hand, you can clear a CA exam if you score 40% or more in it with a cumulative average of 50% or more during IPCC or Final Exam stages.

Its a matter of choice. A choice that you have to make. But on a personal note, I myself am pursuing Baf and CA together. And trust me, its an add on due to the following reasons. It stands out in the market as B.Com is to mainstream. That's how you are different than your other competitors. Its always beneficial to have a good degree and Baf is latestly doing great in the job networkThe portion of your Baf course (upto ty) are -: subjects such as various types of accounts I. e financial accounting is your Accounts paper 1&5, Cost & Management accounting is paper 3, Tax is paper 4, auditing is paper 6 of Ipcc. This means portion runs parallel and you don't have to put in extra efforts for studying baf subjects (except one extra theory subject per semester which is affordable) unlike B.Com. Helps in time managementHave compulsory internships and a handful of presentations (depending from college to college) in the course helping you boost your self confidence, brush your soft skills and gives you a good experience of work zones which is significant in today competitive world. I know attendance in college is mandatory and all for such courses, but if you are pursuing an additional degree along side the college authorities to consider if you talk about it to them (Atleast mine were very supportive about the fact and welcoming open heartedly)
I believe nobody likes to be ordinary. So I think my choice to go along with baf and CA is still one decision I would never regret in the educational passage of my life since I was always interested in accounts. So look into your interests. Go through the syllabus of both courses. And then decide! I assure you that you wouldn't regret it too.
