Yes, sounds like you are flaring too much if your tail is hitting the ground. That means your nose is too high. Are you cutting the throttles
back to idle when crossing the threshold of the runway, so when you are flaring, you speed is dropping and you land. Remember that if
your sink rate is too great, you will not be able to pull it up, right on the runway, it is too late at that point.

i know its a stupid question but is the thereshold the part of the runway where it says somthing like 6l?
