This is the first time that admission in IP University is being done through CLAT instead of their own entrance test which was conducted previously. So we do not have any previous year trends to consider for admission here through CLAT.
But as the admission in NLUs through CLAT closes around a rank of 1500-1600 for the general category and there are around 2000 seats available through IPU CET for both BA LLB as well as BBA LLB. Also that 85% seats are reserved for Delhi Candidates,and rest 15% are for Outside Delhi region. You can expect the Delhi region cut off to go till 4000-5000 rank. And the outside region to go lower that this. This is just an estimate. It may differ according to various factors like the number of Delhi candidates falling in that rank range and more.
Best of luck
