In order to get admission in good B School,There are various criteria for shortlisting and selection after clearing the exam with good score such as past academic records, Extra curricular activity, work experience etc.
Your academic records matters but it also depend on your performance during the interview. I would suggest you to focus only on the Exam Preparation to be able to maximize your score so that you may minimize the impact of past academic records.
Good Luck!
