Dear Student,
Glad to inform you that if you wish to go for MBA you need to complete your graduation first as MBA is a post graduation course so for it you need to complete your graduation first which I hope you already have. You should also surpass the minimum eligibility criteria of having minimum 50% in your graduation. If you fulfill the above mentioned criteria you can apply for CAT and should appear for it and you'll be provided an MBA college based on your percentile. So, it needs quite a good efforts. You may choose any specialization in MBA as per your personal interest.
Hope this might help you.
