Law

Of course, you can. There are certain things which you might have to keep in mind in case you plan to continue them both simultaneously. The Council of the Institute, under Regulation 65 of the Chartered Accountants Regulations, 1988 has permitted Articled Assistants to pursue, with prior permission of the ICAI, only one course concurrently with CA subject to the requirement that the schools being attended for such allowed courses do not overlap with the Principal's office hours.
Therefore, if you plan to go for a regular simultaneous course, be sure to have the classes of one the courses in the evening and the other in the morning. It will be an addition to your value and career prospects. There is no harm in it if you want to go for it. I hope this helps. Just don't let one of them affect adversely the other.
