Dear Nikhil,
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. Now, you know what can be done between mentioned duration. I hope it helps!
