I agree with everything grecoaj said. I got my CFI about 2 months ago. CFII a couple weeks ago. What I did to help with level roll ins on the steep turns is pick two landmarks that will allow a 70-90 degree turn between the two and just roll into steep turns left and right back and forth between the two points. The check ride with the FAA was by far the most difficult I have done, but it was also the most fun. Good luck with it all, it's a lot of work but well worth it!
