Hello

As per last few years records and statistics the cutoff rank is 64 for general students. According to du official website In 5th merit list selection was till 35th rank in general and in 4th merit list till 22th rank in 2018. Since you have a rank of 72 you can expect a seat by the 4th round (if at all). They called upto 75 students rankwise with the combined rank till 35. Since there are 71 students ahead of you you must be on 72nd position. By the looks of it you getting a chance are not great but I would suggest you to wait because you might just get it. All the best.
