Hey Prashanth

Greetings. Hope you're doing well. B.com means bachelors in commerce. Its one of the most opted courses and a lot of students opt it. If you wish to pursue some other professional course along with it, go for something which interests you and also, that is manageable. You know about your capabilities better than anyone, do a course which you can do. CA is a professional course requiring dedication and hardwork, it is of 3 years if you clear the levels in continous years. CS makes you a company secretary which is one of the top most positions in a company. Other courses are professional too, each requiring specific abilities and skills. Whatever you do, do it with your heart. Take time and do a thorough study of all the available courses and only then make a choice. Wish you luck.
