Hello Vishal, as per previous years admission process you will surely get into the required course and college as cut off would not be more than 50. Congratulations and i would suggest you to keep checking their website for further process. 

I would recommend you to get ready with your documents like, certificate of disability, mark sheet and provisionsal/original certificate of class 12th and other identities.

Following is the link of BHUS's admission portal:
