What should I do to take admission for MBA in IIM? I have no knowledge about it, please suggest me about it and about a career after MBA.

Hello! All the IIMs accept CAT scores for their admission processes. Kindly visit this link to know more about CAT. https://www.shiksha.com/mba/cat-exam?rf=searchWidget&landing=ep On clearing the necessary cutoffs, the particular IIMs would call you for their respective interview rounds. Good luck!
