The questions are grouped - Ethics, Quant, etc, and the number of minutes is written for every section, but that is just a recommendation. You get all the booklet, and you can solve in whichever order you like. You can finish each section or you can jump around and solve randomly, whatever works best for you, just pay attention at how you fill those bubbles It's not like Toefl.
Hope it helps, if there's anything unclear please ask.
