To determine your eligibility for MBA admission based on your MAT score, you need to check the admission criteria of the specific college or university you are interested in. Generally, most B-Schools in India consider MAT scores for MBA admission.
A composite score of 580.50 in MAT is considered a moderate score, and your chances of getting admission may depend on the admission criteria of the college, the competition for seats, and other factors such as academic qualifications, work experience, personal interview, etc.
To get a better idea of your eligibility, you can check the admission criteria of the college you want to apply to. Most colleges have a minimum MAT score requirement, and if you meet the requirement, you may be eligible to apply. However, meeting the minimum requirement does not guarantee admission, and you need to compete with other applicants who may have higher scores.
In conclusion, a MAT score of 580.50 may make you eligible to apply for MBA admission in some colleges, but the final decision depends on the admission criteria of the specific college and other factors. I would suggest researching the admission criteria of the colleges you are interested in and applying to multiple colleges to increase your chances of getting admission.
