Dear Aspirant I think you may be get this.

The cut off scores of institutions accepting NATA score differs. Before you know the NATA cut off calculations, you should be aware of the qualifying marks for the examination - A minimum of 25% must be obtained in drawing section (20 out of 80) - A minimum of 25% should be secured in the MCQ section (12 out of 30).

Thank you. Best of luck.
