Accounting & Commerce

You should be at least 2nd year pass out to become eligible for CFA.

After 12th, you have to appear for CPT. It is conducted twice a year then you have to go for IPCC (two groups). After clearing 1 or 2 group, you can start your training and after that you have to appear for your last and final exams in two groups.

Dear Ashish Aharma,
I would suggest you to give first priority to BBA and second priority to B.Com. All the best.

You can have following options to work in IT industry after B.Com:
(a) MBA to join in pre-sales, sales and account management roles.
(b) MBA with industry specialization such banking, healthcare, travel etc with IIBA certification to become a business analyst.
(c) MCA to become developer if you had maths in +2 stage.

Both CA and CS are good options. It depends on your ability and skills. CA has more prospects and job opportunities as compared to CS. But many companies offer amazing salary to CS. If you are trying to pursue B.Com + CA, you will need to study at least 4 hrs every day. Also, you will need to do an article ship to get the CA / CS certification.
