Harphunt makes a good point. It can help a lot to get more than one instructor or aproach to flying. Also it isn't a bad idea to ask for one on one time with one of the instructors to work on specific skills. I recently put a soloed flier on my buddybox and my trainer and had him only fly below 1/4 throttle and make repeated passes at about head high. It was just a bit windy and really made the guy work the ailerons and rudder. It was quite a confidence booster as he really did well with this. His slow speed handling greatly improved. And landing, as we know, is all about slow speed handling.
