Once you have learned to drop in you will need someway of moving yourself in the ramp. A kickturn involves doing a 180 pivot below the coping. To do this, just before you hit the coping put pressure on your tail so that it lifts into a manual. Quickly turn the board 180 and release the pressure on the tail. You should try and learn kickturns on ramps that arent very steep, and you should always learn from the bottom of the ramp and work up.
