Hello, 

Out of 400, 200 marks belong to the boarda nd the other to NATA. The only way to calculate your score is to divide the NATA score by 2 and add it to your board percentage. 

Your board percentage is around 83% and NATA score is 101. Your score would be 50.5 + 83.5 which is 134. 

The cut off for open category is 305-315. As you didn't score enough, you would most probably not be placed in the colleges you mentioned above 

Hope this helped you 

Thank you and keep asking:)
