Instructors who insist on things being done THEIR WAY should be shot!!!! One of those was responsible for me taking hours and hours and hours to learn to land. He insisted that as soon as I came over the hedge I cut the power. Having poorish depth perception - I know now that was my main problem - I could never get the flare height exactly right. A few weeks later, poorer by several hundred pounds and my confidence at an all-time low, I finally flew with another instructor, who told me it was OK to keep a bit of power on as long as I liked if I found that easier, so long as it was off when I landed. Hey presto - I could judge my landings! Yes, eventually I had to learn glide approaches, but that's another story.
There are many ways to skin a cat. If your instructor can't accept that, or give you a good reason for doing it His Way, change instructor.
