No, you can't because you won't be able to manage both simultaneously. It's better to focus on one thing that would be better for your future also.

It is not possible because MBA would need 8-10 hours of studies daily and CA would need 10-12 hours daily. You can't manage both simultaneously.

It takes around 3 years and 6 months if everything happens well.

Yes, you can do B.Com Hons. with CA and most of the students prefer the same way or they choose B.Com pass to give more time and dedication for CA preparation .

You can make it if you are interested in the same. For this, you have to clear the common proficiency test (CPT) and the last date is over now. So, wait for one more year.
