Arrive over the threshold at about the right altitude, and airspeed, and with everything pretty stable.
*ROTFL* absolutely correct, BUT ... that is not the tricky part, as most training planes will settle almost by themselves, if you are that far. Add headwind, crosswind, a little too fast, a little too low and you get the shaking. What helped me in that days was landing at large airports and asking for a very long final - just playing on long final with the aiming point.
Don't try to learn "the perfect landing", it is an illusion and similar to the wow girl - most probably, you will never met her. Landings are dirty fun instead ... ;-).
