The time restriction 30 minutes for 33 questions is the most challenging part of the test. You can skip questions and go back later. It's kind of similar to the GMAT math questions, some of them involved looking at graphs and charts and questions vary in difficulty. The questions are not related to aviation though. A good approach is to practice basic math skills (+ - / X) and be able to do it fast and accurately.
A similar question is city A is 3 hours behind city B and city C is 2 hours ahead of city B. If it is 12 noon in city C, what time is it in city A?
All the best
