Dear Ankit,

Getting 5.3 percentage in class 12 is considered Fail in most of the boards and you require to pass your class 12 to get admission in BMM. I am sorry to say that you may not get admission this year. 

But the world doesn't end here. You can try one again for your boards in improvement exam or can apply again. Great opportunities are waiting for your push. Don't lose hope and keep trying.

All the best.
