Hi Rajalaxmi,
As you have not mentioned the name of examination so it is not possible to guide you properly.
You are in commerce stream so all future options related to commercial field are open for you. First of all you have to pass 10+2 or equivalent from any recognized board/university.
After passing 10+2 you will be eligible to appear in entrance exams for B.Com.,, B.B.A, B.A., etc.
Hope you are cleared from this answer.
All The Best!!
