CA

The main responsibility of an accountant is to provide an accurate and real-time record of the financial transactions of an individual or organisation. He or she needs to be aware of all of the necessary compliance guidelines during these transactions. A chartered accountant instead will focus on providing accurate records of all financial transactions for an individual or business. Thus, this type of accountant is more likely to be found employed in a more commercial capacity. While an accountant may have his or her own practice for a number of years, a chartered accountant is considered more of an accountant for hire. Likewise, they can often provide fee-based services for organisations.

Hi Mini,
One can easily study for both CA and CS together. Since both are related to the accounting profession itself, the subjects are all similar. The total academic syllabus to be studied contains a majority portion which is common to all the two courses.
With systematic planning you can attempt the two courses together along with your graduation/post graduation course in the formal stream. There would not be a clash of examination dates also.
A practical approach would be to attempt two courses together along with the formal graduation/post-graduation.
If you start doing these courses with graduation, you have enough time to make a wonderful career. If you strongly feel that it would disturb your approach in any way, please refrain from doing multiple courses simultaneously.
Hope it helps. Please feel free to revert. Click on the thumbs up or mark it as the best, if you found this useful.
Wish You Luck!
