Don't use a flight sim for the flare.
Its a 2D simulation of a 4D enviroment. When I say 4D the 4th dimension is mother nature.
The trick with the flare is to try and not land with the power off. Also have a look at the attitude your instructor lands at when you get to that attitude hold it while wiggling the rudder pedals.
Then in a loud clear voice say "get down you whore"
Do that three times and off solo you go.
