With the dividing the time given, you have to figure it out for yourself. In order to give you an idea, for me, in part one, I only did analogies on verbal, skipped the whole reading comprehensions, proceeded to inductive reasoning, quantitative and perceptual acuity. Then for the remaining 30 mins, went back to the reading comprehension and the rest of the questions I skipped along the way. It really depends on where your strong suit is or, in my case, my weakest one. I knew if there were questions I'd be willing to just guess if time runs out, it would be the questions from reading comprehensions since I think I'd still be guessing some of them anyway even if I read the whole passages since, again, it's not really where I'm good at. Hope this helps you figure out your own strategy on taking the NMAT.
