Heritage Business School Admission chances

I am sorry, but I would need more information to determine your eligibility for MBA admissions. Generally, eligibility criteria for MBA admissions include a Bachelor's degree from a recognized university with a minimum of 50% aggregate marks (45% for reserved categories), and a valid score in a national-level management entrance exam such as CAT, XAT, GMAT, MAT, or CMAT, depending on the institute's requirements.
If you meet the eligibility criteria, you can start by researching the institutes that offer MBA programs in the specialization of your choice, such as marketing, finance, human resources, operations, etc. You can check their websites for admission criteria, application procedures, and entrance exam requirements.
For example, if you are interested in the MBA program at JBIMS, Mumbai, you will need to appear for CAT or MAH CET, or XAT, and apply to JBIMS through their official website during the admission window. The institute will shortlist candidates based on the entrance exam scores and conduct a further selection process which may include group discussion and personal interview rounds.
If you are not familiar with the entrance exams, you can find more information about them on their respective websites or from coaching institutes. You can also find study material and previous years' question papers to help you prepare for the exams.
It's always recommended to check with the institutes you are interested in for the latest and accurate information on their admission process and eligibility criteria.
