In addition to what winged wombat said I would advise not only studying your next sortie but your next to or three as one might be cancelled due to weather. Furthermore whilst down there you need to build a model aeroplane with the rest of your group which takes a bit of time individually. When not studying however make sure your not being a hermit. Get out there talk to people about their experiences and advise. Not sure on the routine times as im yet to go to flight screening myself, however all this information has come from someone who very recently went through the program with a recommendation.
