Hello karan
Hope you are good.

It should be your decision depending upon your likes and interest.
CA is professional course while BBA is three years degree level course. If you want to do MBA in future you should go for BBA.
CA requires very hard working until you clears all the papers of CA.

Both are good in their way. One is management and one is like working and accounting in a firm.

Decision should be yours.
Hope you choose the best.
Good luck.

Hello,
Look, it totally depends on which field the student is interested and which field he wants to gain knowledge.
If he is good in communication skills and thinks that he can handle business problems then BBA is gonna be best for him.
But if he wants to get technical knowledge about programming,hardware,etc..then he should go for B.tech or BCA course.
Good luck.
