Lot of good info already, but, it is not by chance that generally a good landing, comes from a good stabilized approach. So, fly some standard circuits, same height, same speed drill, and get used to the view. Over the numbers, make sure that your eyes and gaze start to move to the end of the runway. Periphery vision kicks in and keep your gaze there. Try not to look back down into the cockpit, keep looking outside. As you get closer, type dependent, and you pull to idle, gently flare, and just keep it there until you land.
It will come with practice, but on any given day, we can all arrive with a howler.
