Hi Sanskruti,
These certificates most certainly improve an application when you wish to take admission in NLU's.
It will always benefit and add to the admission process.
Also, on a special quota for students have won accolades and awards, they may accepted into the institution.
I hope this helps you out.
All the best.
Let me know if I can assist you with anything else.
