Skerr1t, the questions will be graded. Easy to get you into the swing and progressively harder to guage your skill level.
Question one might be "You are travelling at 30 miles an hour. How long to travel 3 miles."
Question 10 might be "You are in a fighter travelling at 540 kts chasing a passenger aircraft flying at 480 kts. It is 1020. You are 15 miles behind and 100 miles from base and flying directly away. At what time will you catch the passenger aircraft? If you now return to base crusing at 420 kts what is your ETA?"
Give an example of the question you found really hard.
