Yes, you can surely do CA alongwith B.com and JBT but i might not recommend it as it might be difficult for you to cope up. Though CA alongwith B.com is a good combination and many people pursue both of them altogether as a major portion of your B.com course will be covered by your CA course studies. If you want it to be a bit easy you can also do CA with B.com in correspondence but do note that though it'll be easier it has less value than B.com. All the best, hope my answer would help you a bit.

Hello Ashish,

Yes, you can do CA and B.com simultaneously and also you can give JBT exam along with all 

that but it doesn't sounds well.

Wish you all the best.
