In the part of questions with mathematical logic, questions like (if a worker does something during t minutes, then at what time do all the workers finish the job if they start at x time?) and other simpler or more complex questions, where you need only a few notions of mathematics maybe, not very advanced, and logic in thinking. The questions are in English, not very difficult, but you have to keep your concentration because you can make a mistake not in the calculation, but by inattention to the details or to the transformations, in a hurry.
