Isn't nursing something that the AF will take care of with your schooling since I think there is a need for AF nurses. Are you reuping in 2009 or that's when you're done.
If you have all of your pre-reqs done depending on where you are in school the place I teach does a full day lecture, couple of partial lecture/lab days and a full clinical day. They like to suggest 2 hours study for every hour in class but somepeople don't need that much but others need more
