Hello there,

To get a seat through NATA first you have to clear the cutoff by scoring a minimum of 30 marks in mathematics and general aptitude and a minimum of 20 marks in drawing. However you have to score  a total marks of 70 (including 30 in mathematics & aptitude and 20 in drawing) for qualifying the exam. After qualifying you have to individually apply for the colleges where you want to get admission and attend the respective colleges counselling processes inorder to get a seat there for B.Arch. 

Now since you want to get a seat in KL University, for that you have to attend the colleges own counselling process namely KLUEEE counselling. Through that counselling you will be able to get a seat for B.Arch. You can also go through this link and checkout all the details regarding KLUEEE counselling : https://engineering.careers360.com/articles/kleee-counselling

Hope you get your choice of college. Good Luck !!!!!
