Hello Aria ,

 NATA is an entrance examination for pursuing architecture. The examination occurs in two parts, part A and part B. The timing for part A which contais 60 questions is 60 minutes and part B is 120 minutes. As there is only time limit for the parts there is no time limit for each question. So  there is no worry each question doesnt haave a time limit and each part has a time limit. Let you know this and crack the NATA exam. I wish you fr that.
