Hello,

Your final merit mark will be calculated by dividing nata score by 4 and  12 th percentage by 2 and then add them

65/4+70/2= 51.25( merit mark)

It is more difficult to get into colleges of  your choice based on your score. Because to get into decent College of your choice or Government colleges you should have more than 100-150 nata score.
