Dear Diwesh,
According to the revised admission schedule of LLB/LLM: "In view of the announcement of UG results, it is proposed that PG Admission portal shall be reopened for LL.B. and L.L.M. applicants. All the applicants are advised to fill the marks of their graduation/qualifying degree and XII class marks from 17th July till 22nd July 2018, even if they have filled during the registration process. During this time applicants may also be allowed to modify their preferences of Centres filled at the time of registration. No further grievances shall be entertained regarding the same." It means you also had the opportunity to modify preferences of Centres filled at the time of registration. Now you wait for the release of First Admisson List which will be released on July 25. I hope it helps!
