Hello Natasha,

As your 10th marksheet has only your first name, it is preferable that you should use class 12th marksheet, as there would be full name of yours.

The full name of any candidate is mandatory for sitting in any government entrance exam with a valid ID card.

But try to produce new marksheet for class 10th by requesting your respective board as it will be required on future, so it would be great that I should have a full name of yours.

Hope it helps you..

Best of luck..
