Sorry I am not getting that you have done B.Com in computers. But B.Com is Bachelors of commerce.

Confusion created when you have similar type option. Its like you're confuse between North Pole and South Pole. Both these fields as poles apart. If you're good at accounting, statistics then opt for B.Com and if you have creative mind and love to read, write, current affairs etc. Then opt for B.A. Honers in Journalism
or choose B.J. M. C. instead.

HI Manisha,
You don't need to appear for any entrance exam. Although, different colleges and universities conduct their own admission tests for B.Com.

They haven't mentioned a particular percentage, but it is better to score 75+ in any case.

I didn't understand what you wanted to convey. But I'm guessing you want to reapply for a programme. If it's a Bachelor's programme then your class 12th marks and relevant entrance exam score would be considered.
