dear student,

As of 19th May, 2018 with so many reports and predictions out analyzing CLAT 2018, I would say that a marks range of 110–120 should be enough to get a NLU seat. However, you should get around 135–140 marks for Top 3 NLUs.

Remember, nobody can give you exact details unless official merit list is out. Hope this helps, keep calm and wait for the results.

Good luck
