Hey,

As per marks criteria, 200 marks out of 400 belong to the board marks and the rest to NATA.

The cut off is calculated diving the your NATA score by 2 and adding it to your board percentage.

On doing the above mentioned proccess, your score would be 120. The cut off lies between 305-310 for open category. Hence, you might not get a seat there.

Hope this helped you

Thank you and keep asking:)
