Hii

If you wish to get admission in the NLUs, then you are not supposed to fill seperate forms, you just have to fill the CLAT form and give your preference of all the 21 NLUs that are participating in the admission process through CLAT.
If you wish to go to NLU Delhi, then a seperate form is to be filled as well as seperate entrance ( AILET) is conducted.
Also, for the colleges which accept CLAT scores other than NLUs, you need to fill seperate forms.
If you wish to know in particular about some colleges, please specify the names of those colleges and we will give the answer based on your choice and query.

Hope this helps
Thanks!!
