Hi

This year due to so much uncertainties it's really difficult to say as to on what basis admissions would be offered.

As far as 2nd options are concerned, in my opinion you should always have a plan B even if you're sure of something. Life can take twists and turns and who knows you'll actually get more interested in your plan B. In your case, NDA and CLAT both are great options. I think you should definitely study for any one of them, knowledge never goes wasted, it will help you somewhere in your life.

All the Best!
