I am a newby skydiver so am learning much from these threads. I failed my AFF3 last weekend, as my position - proven on the video - was horrible. We spent five minutes redoing some exercises on the ground and my instructor showed me one trick which just clicked in my head. We went right back up and I did it perfectly. Sometimes you just need it explained a little differently. My instructor had me lay flat on the ground, push up with my arms and he said - feel that tightness in your back? Get the same feeling when you jump and you will have the position. I did it, I was relaxed and I was on to the next level. Couldn't believe how easy it felt.
