Hi Aspirant!

There are very low chances that it might cause problem in the NEET UG application. There are almost no chances that on the basis of a missing alphabet your application get rejected.

But I would suggest you to make it correct, either by visiting the Adhar card centre or by approaching your school/CBSE office. As it might cause problem during the NEET UG counselling especially in document verification.

Thankyou!
