Hello Anish Sinha,

I would like to tell you that it won't cause any problems to you.

You can carry a B&W copy of the admit card. We advise yopu to carry some other identification as well so that there is no issue. I will alos advice to take multiple copies so that you can use them for future refrences.

I would suggest you to visit the careers370's link given below which has a detailed explanation of the CMAT admit card.

The link for the same is:https://bschool.careers360.com/articles/cmat-admit-card

Hope this helps and all the very best!
