You'll be fine, Im sure of it. I second the note taking during debriefs...buy a small notebook just for this purpose. I would also write down the things I did right so that I could keep doing those things, but more importantly, the things I jacked up. Before each flight or when chair flying the night prior, I would bust that notebook out & review it. If I screwed it up again on my next sortie, I would write it down again...until I got it right. It's great now looking back in the notebook to see all my rookie mistakes. Also, definitely don't underestimate the power of sleep. You'll have to decide when you need to study a little more versus when to shut the books & sleep. I usually chose the latter, which was worth it for me.
