Hii aspirant
Hope you are doing well amid covid-19 pandemic
First of all congratulations for securing good marks in NATA and board examinations
With 117 marks in NATA and 90% in boards you have made the cut to get a seat in and even outside Kerela
So securing 60 marks is considered to be sufficient to get into good colleges  for B.arch
Your score can be calculated as
NATA marks /4+ Board marks /2 to get a score
So in you case it will be
117/4+90/2
29 + 45 = 74 marks and it is a very good score
But here also some points are to be kept in mind
A minimum of 25% must be secured in MCQ portion (32 out of 125)
A minimum of 25% must be secured in Drawing portion (18 out of 75)
So this criteria is also to be fulfilled
But as per my knowledge you must have fulfilled this as well

So you are good to go ahead
Hope it helps
