One thing I forgot to mention as you will no doubt find during the course of your training (noticeably if you go beyond PPL) is that Instructors often seem to change thier minds about how they do things: Whats right one week will be wrong and changed the second week, by the third week it will be a case of "whats going on? you wern't doing that 3 weeks ago, who showed you that?"
Its all very amusing so have fun!
