Hello,

To know your merit mark you need to divide Nata score by 4 and divide 12 th percentage( out of 100) by 2 and then add them to get the final score

For example,

Since you got 112 as Nata score and you didn't mention your 12  th board percentage so I will assume it as 70%

Now calculating based on the above mentioned nata score and board percentage your merit mark will be:

112/4+70/2= 63

So to calculate the merit mark it needs natascore and 12 th board percentage (out of 100)

Hope it helps

Good luck!
