You can't do good landings if you have just done a bad circuit. Therefore if you haven't mastered the Attitude/Power/Trim bit and you start the downwind leg at the wrong height, then you'll be in the wrong frame of mind to do a good landing.
Building blocks, falling into place.
You'll be able to land when you are able to land. You may actually learn lots of other stuff before that.
I did a navex to landaway over 200 miles from base and back that afternoon, six months before I did my first solo. That was eyeopening and gave me a great understanding of what I was working towards.
