and what I did when I was a young troop was to focus heavily on some of the subjects. It is better to know some subjects than it is to try and cram everything in a week. Like the previous poster said notecards work and I remember things I write down, so if I am having trouble on a certain question I will copy down a few times. What Armyof1 stated is the truth but you do not have time for that and I doubt they would ask a PFC something that is not readily available to them. Good luck.
