Hi Neha,

55 is a decent composite score, but it's not as good enough to be assured of a seat in DU. Your admission would also depend on the course you want as well as your category. 

However, a clearer prediction can be made only once we know of your rank. They will be out around 20th July. It is these ranks that determine the cutoff for each college and not the score. Ranks depend on factors like difficulty of the exam, number of candidates, average performance etc. 

Wish you all the best!
