Strange, I thought you would have been briefed at the careers office. I believe they have a workbook with lots of time and distance questions, basic tactics etc.
What you need to do is know what is going on in the world and where in the world it is going on. Don't ignore the UK. Make sure you know where the cities are. Head start if you know where the RAF is too.
One tip, in 6 minutes the distance you travel is one tenth of your speed in miles per hour.
