Is there any use of class 12th marks if I get into NLSIU?

One of my cousins graduated from NLSIU and here’s what I got to know from him. To get into any NLSIU you need to sit for the all-India entrance exam called CLAT.

• You can appear for the CLAT exam without being a 12th pass out. But if you get selected and wish to join NLSIU, Bangalore, or any other NLU you need 12th marks.
• For Unreserved, OBC, or Specially Abled Persons (SAP) and other categories: a minimum of 55% marks. 
• For SC/ ST category, a minimum of 50% marks is required.
• On the date of admission, the candidate must have passed or appeared in the final year examination of the qualifying examination.

So it might not make much of a difference after you get NLSIU but it matters when you prepare to get into it.
