Skills tested in the entrance test includes general proficiency, logical reasoning, quantitative analysis and basic Mathematics and the students are judged on parameters like career focus, maturity and confidence, general awareness and intellectuality in the personal interview.

There are lot of private colleges/universities offering IT/B.Sc. They don't give * about weather you are from commerce or arts stream.

Hi Ayush!
If your rank is eligible for admission, you will receive a mail or call from the university inviting you for the counselling. Please note that the eligibility does not mean you will surely get admission. Higher the rank, higher the possibility of admission. Also, keep a tab on the official website of the university for updates.

According to me, B.Sc (General) is a better option.
Else, it depends on your choice.
