Yes, you can do both at the same time.

There is no specific stream to join CS. ICSI has opened its door for every student. You can join CS after completing your graduation. But as per my opinion you should go for MCA or other Software courses as you may be having deep knowledge of computer. Rather rushing towards corporate world with little knowledge, in my opinion you should give your best in IT sector. But it completely depends upon your interest. You can pursue CS and have a bright future ahead.

It depends upon your area of interest. After 12th (commerce) you have many options. You can go for ACCA, CA, CS or B.Com+MBA.
