Well, I failed about three solo checkrides!!! I think it was nerves basically. So I ran around trying to work out how to land with my brain, but it didn't do any good. Practice did it for me, practising till I got to the point that my hands and feet and eyes knew what to do, even when I was nervous.
BTW, despite my name, I'm talking about solo for my PPL(A). Landing helos is easier; you can slow down first
